摘　　要：根据半主动激光导引头目标探测的工作原理,本文基于四象限探测器设计了一种以FPGA为核心处理器,高速A/D采集的数字化导引头信号处理系统。该系统可实现脉冲激光编码的识别,目标的捕获、跟踪以及对目标方位信息的解算等功能;首先简要介绍了四象限探测的基本工作原理,接着给出了系统的总体设计和分模块硬件电路的详细描述,给出了系统软件设计的流程框图;设计实现了导引头的基本功能,经过试验调试验证了其技术可行性。According to the working principle of semi-active laser seeker target detection,this paper designs a digital signal processing system based on four-quadrant detector with Field-Programmable Gate Array（ FPGA） as the core processor and high-speed A/D acquisition. The system can realize the basic function of laser coding recognition,target acquisition,tracking and solution of target azimuth information. This paper first briefly introduces the working principle of four-quadrant detection,then the overall design of the system and the detailed description of the module are given,and the flow chart of the system software design is given. The basic function of the seeker is designed and verified,and the technical feasibility is verified by the test and debugging.
