It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.

To achieve the above object, the present invention provides a portable radar apparatus 1, as shown in fig. 1-2, comprising:

An apparatus body 10.

The power adapter 20 is electrically connected to the device body 10, and is used for supplying power to the portable radar device 1, and may be selected according to the voltage required by the portable radar device 1, and a 48V power supply may be used to meet the requirement.

the antenna panel 30 is detachably disposed at the upper end of the apparatus main body 10, and the antenna panel 30 is provided with an antenna unit 31 electrically connected to the apparatus main body 10, and configured to transmit a pulse signal and receive an echo signal.

and a support mechanism 40 detachably provided at the lower end of the apparatus main body 10 and supporting the portable radar apparatus 1. The apparatus body 10 is detachable from the antenna panel 30 and the support mechanism 40, respectively, so that the portable radar apparatus 1 can be mounted, dismounted, transferred, and transported, making it easier to use at a predetermined place.

the device body 10 is provided with a processing unit 11 and a transmission interface 12, wherein the processing unit 11 is configured to process the echo signal received by the antenna unit 31, generate navigation information corresponding to a target, and output the navigation information to the operation terminal 50 through the transmission interface 12 for display.

after the portable radar apparatus 1 is mounted on the site, the power adapter 20 supplies power to the portable radar apparatus, and at this time, the operation terminal 50 is connected to the transmission interface 12 to perform an operation, for example, the power of the antenna unit 11 is set to adjust a range to be monitored, the operation mode of the portable radar apparatus 1 is set to adjust a direction to be monitored and data to be collected, and a signal is set to output a corresponding signal to the antenna unit 11.

when the portable radar device 1 is set to operate, the processing unit 11 forms a pulse signal, radiates the pulse signal to the outside through the antenna unit 30, and receives an echo signal corresponding to the pulse signal. The pulse signal hits the target aircraft within the radiation range, and an echo signal corresponding to the pulse signal is formed, and the antenna unit 30 further collects the echo signal and feeds the echo signal back to the processing unit 11. The radiation of the pulse signal and the echo signal in space is in the form of electromagnetic waves.

the processing unit 11 can determine the position of the target aircraft according to the echo signals, and through continuous monitoring, the position points are connected in series to form navigation information. At this time, the navigation information acquired by the processing unit 11 may be fed back to the operation terminal 50, and displayed through a display screen on the operation terminal 50, so that the relevant personnel may confirm the target aircraft.

in the processing unit 11, the processing unit may include a clipping module, a low noise amplifier module, a frequency mixing module, a filtering module, and a DBF (Digital Beam Forming) module, where the clipping module, the low noise amplifier module, the frequency mixing module, and the filtering module form a receiving channel, so that the acquired echo signal (analog signal) is converted into an intermediate frequency signal, and the DBF module processes the intermediate frequency signal to form a Digital signal, so as to implement feedback and visual display.

According to the portable radar equipment provided by the invention, the detachable antenna panel is arranged at the upper end of the equipment main body, and the detachable supporting mechanism is arranged at the lower end of the equipment main body, so that the portable radar equipment can be simply disassembled and assembled, is convenient to carry and is more flexible to apply.

in the process of practical application, since the monitoring range needs to be determined according to the actual situation of the field, the antenna panel 30 of the portable radar device 1 needs to be freely adjusted in the pitch angle. Further, the antenna panel 30 includes a panel main body 32 and an adjusting mechanism, wherein the panel main body 32 may be a metal plate, and the metal plate may improve the effect of the antenna unit 11 to radiate electromagnetic waves outwards, and at the same time, may also implement radiation guiding;

And an adjusting mechanism located at the rear side of the panel main body 32 for adjusting the pitch angle of the panel main body 32.

Specifically, as shown in fig. 3 to 4, the adjusting mechanism includes a fixing rod 34, a fixing seat 35, and a fastening bolt 33;

The free end 341 of the fixing lever 34 is used for connecting the apparatus body 10, and the adjusting end 340 of the fixing lever 34 has two fastening arms 351 extending in the axial direction of the fixing lever 34;

The fixing seat 35 includes a connecting portion 350 and an adjusting portion, the connecting portion 350 is connected to the panel main body 32;

Wherein, the adjusting part is provided with two fastening arms 351, and the adjusting end 340 is connected with two fixing arms 343 through fastening bolts 33.

Since a large number of antenna arrays need to be disposed on the panel body 32, and the panel body 32 itself is a metal plate, which results in a large weight of the panel body 32, a stable manner is required to support the weight of the panel body 32, and the installation manner should not be too complicated, so that it can be quickly installed to achieve quick deployment of the portable radar apparatus 1.

the fixing seat 35 may be fixed to the panel main body 32 in a form of a bolt, or may be welded to the panel main body 32, but is not limited thereto, and any fastening connection between the fixing seat 35 and the panel main body 32 may be implemented.

Bolt holes adapted to the fastening bolts 33 are provided in the fixing base 35 and the fixing rod 34. When mounting, the two fastening arms 351 of the holder 35 are first snapped to the free end 341 of the fixing rod 34, and the bolt holes of the holder 35 and the fixing rod 34 are aligned. The fastening bolt 33 is inserted along the bolt hole and tightened so that the fastening arm 351 can be made to clamp the free end 341 of the fixing rod 34 received therein to firmly connect the two together.

Since the flight of the target aircraft is difficult to predict, it is necessary to enable the portable radar device 1 to perform a panoramic scan. Further, the apparatus main body 10 includes a driving mechanism 36, and the driving mechanism 36 is connected to the adjusting mechanism for driving the panel main body 32 to rotate in the horizontal direction by the adjusting mechanism.

The drive mechanism 36 may be a motor with a gear train (not shown) disposed between the motor and the adjustment end 340 of the fixation rod 34.

A certain rotation speed is set for the portable radar device through the operation terminal 50, so that the driving mechanism (i.e., the motor) 36 can drive the transmission of the gear set to drive the adjusting end 340 of the fixing rod 34 to rotate in the horizontal direction, and further drive the panel main body 32 to rotate, thereby realizing panoramic scanning, enabling the portable radar device 1 to form a quasi-circular monitoring range by taking the portable radar device as a circle center and taking the radiation length as a radius, and further more comprehensively monitoring the scene, and more easily finding and monitoring the target aircraft flying into the scene.

In order to better feed back the navigation information of the target aircraft, the device body 10 further includes a positioning unit 13 connected to the processing unit 11, and configured to collect a positioning signal and position the position of the portable radar device 1 through the processing unit 11. For example, the positioning unit 13 may adopt a differential GPS module or a receiver using a Beidou satellite to determine the location, direction and time, and further, the processing unit may determine a possible detection target of the target aircraft by combining the acquired map and navigation information around the site, so that monitoring by the staff is more targeted.

Specifically, as shown in fig. 1, the positioning unit 13 includes a positioning antenna 131 and a link 132;

The link 132 is foldably provided at an upper end of the apparatus body 10, and the positioning antenna is provided at a free end of the link 132. The foldable connecting rod 132 can extend the positioning antenna 131 to a higher position, so that the connecting rod 132 can be longer to avoid the interference caused by the antenna unit 11, and the connecting rod 132 can be more portable.

Further, as shown in fig. 5, the antenna unit 31 includes:

a transmit antenna array 310 for transmitting pulsed signals;

and the receiving antenna array 311 is located at the lower side of the transmitting antenna array and is used for receiving the echo signal corresponding to the pulse signal. As described above, after the pulse signal is radiated outward, if the target aircraft exists in the radiation range, the pulse signal hitting the target aircraft is reflected to form the echo signal.

the transmitting antenna is a wide-beam antenna, and the arrangement of the wide-beam antenna can enable the transmitted electromagnetic waves to have larger radiation area, so that the target aircraft can be found more conveniently and rapidly; the receiving antenna is a narrow beam antenna, and the narrow beam antenna can enable the portable radar device 1 to accurately position the target aircraft, so that the position of the target aircraft can be confirmed more conveniently.

Further, the receiving antenna array 311 is an array of 80 columns × 32 rows, each row is used as a receiving sub-array, and each receiving sub-array forms a receiving channel;

the 32 receiving channels form 8 echo signals, the receiving beam width of one echo signal corresponding to the adjacent 4 receiving sub-arrays is 2-5 degrees, and the interval between the adjacent receiving beams is 1-3 degrees. Preferably, the receive beam width of each echo signal is about 4 °, and the angular separation of adjacent receive beams is 2 °. When the target aircraft is found, the angle interval of each receiving beam can be adjusted to 1 degree, and the pitch angle of the target aircraft with higher precision can be obtained through the pitch angle and the difference side angle. 8 echo signals are formed by 32 receiving channels, so that the beam direction can be flexibly controlled, and the tracking of the target aircraft is more convenient.

Further, the receiving antenna array 311 is further configured to receive the correction beam signal; the correction beam signal is used to correct the receive channel. Thus, the receiving channel can be corrected during the target detection.

The portable radar device 1 mainly realizes the amplitude-phase consistency correction of a plurality of receiving channels by adopting a built-in automatic correction mode. At the end of each frame timing, a Pulse Repetition Interval (PRI) is added as a correction time, the DBF component sequentially selects a signal of a receiving channel and sends the signal to the processing unit 11, I, Q information of a corrected beam signal is calculated and sent to the data processing component and the terminal, each corrected PRI can realize the correction of one receiving channel, that is, the time of 32 frames required for correcting 32 receiving channels of the whole receiving antenna is realized, and the terminal calculates the amplitude and phase compensation data of each channel according to I, Q information calculated during the correction of 32 channels and sends the amplitude and phase compensation data to the DBF component. In order to reduce the error of single correction, a cyclic correction and coefficient weighted average mode can be adopted to obtain calibration data with higher accuracy and improve the beam forming quality.

In order to enable the portable radar apparatus 1 to be more conveniently provided and to have stability, further, the support mechanism 40 is a tripod.

of course, the supporting mechanism 40 may be a vehicle-mounted fixing frame for fixing the portable radar apparatus 1 to a vehicle so as to have a movement monitoring mode.

in addition, the portable radar device 1 may be provided with a processing device, such as an interfering device, so as to further include a processing means for interfering with the target aircraft entering the monitoring range, preventing the detection thereof, or making it impossible for the user to acquire the detected data.

according to the portable radar equipment provided by the invention, the detachable antenna panel is arranged at the upper end of the equipment main body, and the detachable supporting mechanism is arranged at the lower end of the equipment main body, so that the portable radar equipment can be simply disassembled and assembled, is convenient to carry and is more flexible to apply. Moreover, a disposal device can be installed on the device, so that the device can destroy the detection of the target aircraft, and the monitoring range is better protected. Alternatively, by providing a different form of support mechanism, stability or mobility is provided.

although the embodiments of the present invention have been described above, the above description is only for the convenience of understanding the present invention, and is not intended to limit the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
