| Abstract: | A known radar signal sorting scheme based on pulse repetition interval(PRI) tracker is given,and the integral part of the circuit is introduced. The method to realize the filter,the first pulse capture circuit and the PRI tracker is elaborated in detail. Multi-channel PRI tracker is mainly realized in FPGA for parallel signal sorting. The realization of whole hardware known radar signal sorting, realize the real time known radar signal sorting in high pulse dense signal environment, the reliability and flexibility are improved. The signal sorting and processing ability of the electronic warfare device is enhanced. |
