RealTime SSR Signal Processing System Based on MultiDSP
-
摘要: 以4片数字信号处理器(DSP)和2片现场可编程逻辑阵列器件(FPGA)为核心处理器,设计 实现了二次监视雷达SSR(Secondary Surveillance Radar)实时信号处理机.该系统基于2 块DSP+FPGA模式的实时信号处理板,实现了对原始二次监视雷达应答信号的各种处理:反同 步窜 扰处理,反非同步窜扰处理,计算目标的方位、距离,进行目标的高度、代号解码以及实时 产生航管询问编码,并生成各种信息的统计报告.Abstract: A real-time secondary surveillance radar (SSR) signal processing system was des i gned by using four digital signal processing (DSP) and two field programmable ga te array(FPGA)．The system consists of two real-time signal-processing boards of DSP+FPGA mechanism．It implements processing of signals from SSR responder, suc h as anti- garble, defruiting ,calculation of azimuth and range,decoding of h eight and special -code of planes. The system can produce inquiring -code for air traffic control(ATC) and report statistical information timely.
