摘要
叙述了远程航路监视一次雷达信号硬件架构及主要技术实现,结构上采用双系统冗余同步设计,硬件组成上采用基于通用CPCI规范的分机,输入输出采用高速光纤和网络接口,信号处理采用FPGA+DSP紧密耦合结构。系统采用了双通道频率分集技术。目标通道采用低副瓣非线性调频时域脉压,滑窗式自适应AMTD处理,自适应门限图,单极点滤波,点迹凝聚和点迹后处理等技术。系统具有独立的气象通道。
The hardware structure and the implementation of the main technologies of the signal processing system for a long-range air route primary surveillance radar（ARSR） are introduced with the dual-redundant synchronous systems adopted structurally,the universal CPCI standard adopted for the composition of the hardware,the high-speed fiber and network interface adopted as the I/O,and the tightly coupled structure of the FPGA＋DSP adopted in the signal processing.The dual-channel frequency diversity technology is adopted in the system,and the technologies of the low-sidelobe non-linear FM time-domain pulse compression,the sliding window adaptive AMTD processing,the adaptive threshold map,the single-pole filter as well as the plot clotting and post processing are adopted in the target channel.Besides,the system has the independent weather channel.
