Technical Field

The invention relates to the field of signal processing, in particular to a device for fusing pulse signals among multiple modules.

Background

In the field of signal processing, pulse signals of multiple channels are generally required to be processed simultaneously, but the processing capability of one module is limited, and the processing of all the channels cannot be completed simultaneously, so that how to efficiently fuse the signals of each module is a problem to be solved for ensuring the subsequent direction finding correctness and improving the signal processing capability.

In the prior art, a common implementation manner is that a digital receiver of each module independently completes detection and reference detection of pulse signals of respective channels, the digital receiver of each module generates pulse signal description words of respective channels and then sends the pulse signal description words to a signal fusion device for fusion, and the signal fusion device performs fusion of the pulse signal description words of a plurality of modules according to information such as frequency, arrival time and the like, and finally forms pulse signal description words including amplitudes and phases of all channels.

According to the traditional method, when the pulse signals are near the sensitivity, the situation that only part of modules can detect the signals and the rest of modules cannot detect the signals possibly occurs, at the moment, the signal fusion device can only receive part of pulse signal description words output by the modules, and finally the fused pulse signal description words cannot contain the amplitude and the phase of all channels, so that the precision of subsequent direction finding is reduced or errors are caused.

the signal fusion device receives the detection frequency point information generated by the signal detector as the input of the signal fusion device, and generates frequency guide information to be input into the parameter measurer of each digital receiver.

Furthermore, the signal fusion device compares the amplitudes of a plurality of detection frequency points generated by a plurality of digital receivers, and guides the parameter measurer to measure the frequency points by taking the detection frequency points with the maximum amplitude as processing frequency points in the current system.

Further, the parameter measurer compares the frequency and the module number of the current processing frequency point with the frequency and the module number of the current detection frequency point, measures corresponding parameters for the same processing frequency points and forms a pulse signal description word, and extracts amplitude and phase information of the frequency points for different processing frequency points to transmit to the parameter measurer of other digital receivers.

And comparing the same processing frequency points in the parameter measurer, and fusing channel amplitude and phase information transmitted by other digital receivers to form a pulse signal description word containing the amplitudes and phases of adjacent digital receiver channels or all digital receiver channels.
