It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

A first embodiment of an interference coordination method between an airborne Beidou device and other airborne iridium satellite devices provided by the present application is introduced below, fig. 1 is a flowchart of the first embodiment, and fig. 2 is a schematic diagram of a system architecture of the first embodiment.

As shown in fig. 2, the system architecture of the present embodiment includes an airborne Beidou device and an other Iridium device, which are located on different airplanes. The airborne Beidou equipment further comprises a phased array antenna, a short message receiving and transmitting module and other aircraft iridium equipment detection modules. The phased array antenna comprises a transmitting array for realizing short message transmission and a receiving antenna for realizing short message receiving. And the other machine iridium device detection module comprises a transmitting beam control unit.

As shown in the solid line part of fig. 2, the short message transceiver module transmits the radio frequency signal in the short message through the transmitting array, and receives the radio frequency signal in the short message through the receiving antenna. In the process of signal transmission, the transmission beam control unit can realize beam control on the transmission array.

Based on the above, the method flow of the present embodiment is described below. The embodiment is realized by the detection module of other iridium equipment based on the local machine, and when the short message receiving and transmitting module does not transmit the short message, the detection module of other iridium equipment works. As shown in fig. 1, the present embodiment includes the following steps:

s101, monitoring the working frequency, the working bandwidth and the azimuth angle of other aircraft iridium equipment.

Specifically, the working frequency, the working bandwidth and the azimuth angle of the other iridium device can be periodically acquired, and the acquisition mode can be active measurement or passive reception of data sent by the other iridium device.

S102, judging whether the working frequency and the working bandwidth reach preset conditions or not, wherein the preset conditions are that the frequency of the short message transceiving modules of the iridium satellite device and the iridium satellite device is the same as that of the iridium satellite device or the difference between the short message transceiving modules of the iridium satellite device and the iridium satellite device is smaller than a threshold value, if yes, entering S103, and if not, continuing monitoring.

S103, forming a beam null in the direction of the other iridium device by utilizing the transmitting beam control unit to control the transmitting array of the phased array antenna according to the azimuth angle.

The formation of the beam null is to reduce the transmission power in the direction of other iridium devices, thereby achieving the purpose of reducing interference. As for the transmission power in other directions, the transmission power may be maintained or may be increased appropriately, which is not limited in this embodiment.

In practical application, the other-aircraft iridium device detection module also comprises a digital front-end unit for digital frequency conversion and pretreatment.

The method for interference coordination of the airborne Beidou equipment and other iridium equipment is applied to a detection module of other iridium equipment, achieves interference coordination of the airborne Beidou equipment and other iridium equipment based on a phased array antenna, specifically detects working frequency, working bandwidth and azimuth angle of other iridium equipment through the detection module of other iridium equipment, controls a transmitting array of the phased array antenna to form wave beam null in the direction of other iridium equipment when the same frequency or the difference between the short message receiving and transmitting modules of other iridium equipment and a local machine is smaller than a threshold value, achieves suppression or cancellation of transmitting power in the direction of other iridium equipment, and reduces communication interference between the local machine short message receiving and transmitting module and other iridium equipment.

An embodiment two of the interference coordination method for the airborne Beidou device and other airborne iridium devices provided by the application is described in detail below, and the embodiment two is realized based on the embodiment one and is expanded to a certain extent on the basis of the embodiment one.

First, for the process of S101, that is, the monitoring process of the operating frequency, the operating bandwidth, and the azimuth angle of the other aircraft iridium satellite device, the present embodiment provides the following two implementation manners:

the first implementation is as follows:

referring to fig. 2, an iridium device calculation unit is disposed inside the other-aircraft iridium device detection module. The operating bandwidth, the operating frequency and the other-machine positioning information of the other-machine iridium satellite device are broadcasted by the other-machine iridium satellite device through the ADS-B, and the operating bandwidth, the operating frequency and the other-machine positioning information of the other-machine iridium satellite device are obtained by the iridium satellite device computing unit through the ADS-B. And then, acquiring local positioning information through the avionic system, and calculating the azimuth angle of the iridium device of the other computer according to the local positioning information and the other computer positioning information.

The azimuth calculation process is as follows: assuming that the other-machine positioning information is (x1, y1, z1) and the local positioning information is (x2, y2, z2), generally regardless of the z-axis, the azimuth angle calculation process is:

the second implementation is as follows:

measuring the working frequency and the working bandwidth of other iridium equipment by using an iridium bandwidth and frequency measuring unit; and measuring the azimuth angle of other iridium equipment by using an iridium azimuth angle measuring unit.

As shown in fig. 4 and 5, the specific measurement process of the operating frequency and the operating bandwidth is as follows: the iridium satellite bandwidth and frequency measurement unit controls a receiving array of the phased array antenna to work only by one array element through the receiving beam control unit, the amplitude of the array element is adjusted to be maximum, and the amplitudes of other array elements are adjusted to be minimum. In an overlapping area of the transmitting frequency of the short message transmitting-receiving module and the transmitting-receiving frequency of other iridium satellite equipment, the iridium satellite bandwidth and frequency measuring unit measures the receiving power through digital detection. If the receiving power exceeds the threshold G, measuring the working frequency and the working bandwidth of other iridium equipment through an FFT (Fourier transform); if the received power does not exceed the threshold G, the above steps are repeated after waiting time T (the value is less than the short message transmission interval).

It is worth mentioning that the operating bandwidth of the other-machine iridium satellite device is generally divided into a plurality of sub-bands, and the operating frequency and bandwidth of each sub-band are known. The received iridium satellite signals are converted into a power domain through an FFT module, then power is summed in each sub-band in the power domain, the sub-band with the largest summation power is the working bandwidth (including working frequency and working bandwidth) of other iridium satellite equipment, and the summation power is the power of the iridium satellite equipment.

For the specific measurement process of the azimuth angle, the present embodiment provides the following two implementation manners:

the first is a method of simulating a phased array, when the system architecture is shown in FIG. 4. When the other machine iridium device and the short message receiving and sending module have the same frequency, the iridium azimuth angle measuring unit forms an azimuth scanning beam through the receiving beam control unit, and the direction scanned to the maximum power is the iridium device azimuth angle. If the receiving array element of the phased array antenna can form a scanning beam of 10 degrees, the azimuth angle of the iridium device can be obtained only by scanning 36 times.

The second is a digital phased array approach, as shown in fig. 5. If the volume of the phased array antenna allows, the iridium azimuth angle measuring unit and the receiving beam control unit can be placed in the phased array antenna, and the azimuth angle measurement is completed by a digital phased array method.

For the process of S103, that is, the process of forming the beam null, the following expansion description is made in this embodiment:

and according to the working bandwidth, the working frequency and the azimuth angle obtained in the previous steps, when the frequency of the other iridium device and the short message receiving and transmitting module is the same or the working bandwidth difference is less than f0, the emission beam control unit forms beam adjacent trap in the working direction of the other iridium device through a wave control algorithm. Specifically, the attenuation may be (S-L) dB. Wherein S is an empirical value or the power of the other iridium satellite device, L ═ f/f0 × S, f0 is the threshold, and f is the phase difference between the other iridium satellite device and the short message transceiver module.

Therefore, when the iridium satellite device and the short message transceiving module of the other machine have the same frequency, L is equal to 0; when the interval between the other iridium satellite device and the short message transceiving module is f0, L is S.

In the following, the interference coordination system of the airborne Beidou device and the other airborne iridium device provided by the embodiment of the application is introduced, and the interference coordination system of the airborne Beidou device and the other airborne iridium device described below and the interference coordination method of the airborne Beidou device and the other airborne iridium device described above can be referred to correspondingly.

Specifically, the interference coordination system of the airborne Beidou equipment and other iridium equipment in the embodiment comprises an other iridium equipment detection module, a short message transceiving module and a phased array antenna, wherein the other iridium equipment detection module further comprises a transmission beam control unit;

the other-machine iridium satellite equipment detection module is used for monitoring the working frequency, the working bandwidth and the azimuth angle of other-machine iridium satellite equipment; and the transmitting beam control unit is further configured to control the transmitting array of the phased array antenna to form a beam null in the direction of the other iridium satellite device according to the azimuth angle if the working frequency and the working bandwidth reach preset conditions, where the preset conditions are that the other iridium satellite device and the short message transceiver module have the same frequency or a difference between the other iridium satellite device and the short message transceiver module is smaller than a threshold value.
