摘　　要：为了提高微波雷达信号处理系统的实时性和稳定性,文章设计并实现了一种基于DSP+FPGA系统架构的雷达实时信号处理系统。本系统以GCl012B、FPGA和DSP器件为硬件核心,采用软硬件相结合的方式,具有很好的控制和运算能力,能够实现对非合作运动目标搜索、跟踪等参数的测量以及角误差求取、AGC控制等功能。实际应用验证了该系统设计的正确性和可靠性。同时该系统易于实现,具有很好的灵活性、稳定性和实用性。In order to improve its performance of real- time and stability, a radar signal processing system based on DSP ＋ FPGA is designed and applied in this paper. Based on GC1012B and DSP ＋ FPGA,this system has the better control performance and operation performance. Moreover, this system is help to the parameter measurement of non - cooperative moving target,the angle error acquirement and the AGC controllability. The correctness and reliability of the system design are verified through practical application. At the same time, the system can be realized easily and has flexibility, stability and practicability.
