Research on PRI Tracker System Design of Multi-Mode Radar Signal

As the rapid development of radar technology, advanced multimode radars are increasing dramatically and becoming gradually the dominant branch of radar field. There is a great challenge ahead in jamming and inhibiting these radars in EW and the performance of jamming and inhibiting radars is dominantly determined by the PRI tracker system. In this paper, we present a novel PRI tracker system for tracking multimode radar signal. The proposed tracker employs a tracking radar database and gate export of 60 channels which adopt synthesis gate output mode. Tracker system is implemented by DSP and FPGA. The simulation results show that it can realize the no lacuna tracking of multimode radars.
