基于FPGA的双波束激光引信目标识别算法研究

摘要

Under some engineering application background,in order to identify the low altitude and sea skimming target effectively and eliminate the ocean waves＇ interfere in complex sea conditions,the dual beam laser fuze has been proposed.The working principle and system components are analyzed in this paper.On the basis,the speed identification criterion is proposed,and the target recognition arithmetic program is written by VHDL.Based on the FPGA technology,this program has also been simulated,debugged and tested.The test results proved that the target identification arithmetic have been validated preliminarily,which can identify the targets in a scheduled time.%为在复杂的海面作战条件下有效识别低空掠海飞行的目标和排除海浪干扰,结合一定工程应用背景,分析了双波束激光引信的系统构成和工作原理;重点研究了双波束激光引信目标识别算法,提出了速度判断准则,基于FPGA技术采用VHDL语言编写了目标识别算法程序,并进行了程序的仿真、调试和实物测试,测试结果表明：基于目标识别算法的信号处理系统能够在预定时间内做出判断,初步验证了其原理的可行性。
