基于FPGA+DSP的通用SSR信号处理机

A universal SSR signal processor based on FPGA-DSP

针对二次雷达的通用处理要求,采用流行的FPGA和DSP结构的处理机,并且合理设计处理流程和算法,有效地整合二次雷达接收、发射、信号处理、点迹处理的功能,并适于FPGA流水处理和DSP事务处理。该处理机结构简单、紧凑,功能强大。经测试,能有效处理AC模式和S模式应答信号,实施S模式询问管理及相应功能。

Aiming at the universal processing requirement of secondary surveillance radar, the signal processor with framework of FPGA-DSP was adopted, and the processing flow and approriate algrithm were designed, in which the functions of reception, transmission, signal processing and tracce point processing of the secondary surveillance radar were integrated. It is suitable for FPGA flow processing and DSP transection processing. It has a simple and compact structure, which can effectively handle the respond signal of AC mode and S mode which executes interrogation management and corresponding fuctions.
