[Abstract]:The radar signal processor is an indispensable part of active phased array radar due to the rapid change of beam pointing , excellent interference suppression performance and flexible signal processing mode . With the operation ability of DSP and FPGA and the improvement of memory resources , radar digital signal processing technology has developed rapidly in the field of engineering realization .
In this paper , based on FPGA Kintex7 + DSP TMS320C6678 , the corresponding function of the signal processor is realized by FPGA programming based on FPGA Kintex7 + DSP TMS320C6678 . In high pulse repetition frequency pulse Doppler ( HPRF - PD ) mode , the matching filtering and distance tracking correlation processing of the beam wideband signal and the speed searching process of narrow band and beam are completed on FPGA .
The pulse compression of three channel signals and the MTD processing of 256 cycles are completed in the chirp mode .
In the linear frequency modulation continuous wave ( LFMCW ) mode , the FFT processing and the 64 - cycle MTD processing of the upper frequency sweep period and the lower frequency sweep period beat signal are realized , and the signal processing data is transmitted to the DSP through the Samp high - speed interface .
The function of each processing module of FPGA is debugged and verified on the hardware platform of the signal processor , and compared with the result processed on matlab . The FPGA phased array radar signal processing module can meet the real - time processing requirements , and provide the guarantee for the realization of the whole function of the signal processor .
