Simulation of multichannel radar echo processing based on Simulink

In the simulation of multichannel radar system based on Simulink, common signal processing module is difficult to achieving the data transmission of multichannel signal and data processing part because of its single input/output structure. This problem leads to the Simulink simulation of the whole process of radar echo processing cannot be established. Integrity and speed of the simulation are severely limited. This paper establishes a signal processing Simulink simulation platform by the Level-2 M S-Function custom modules and realizes the whole process simulation of the echo processing based on the radar muzzle velocity measurement system. 16 channels radar echo data are processed on this simulation platform and the results are in the allowable range of reasonable error. The correctness of the whole process simulation is verified.
