：激光引信是现代激光制导系统的重要组成部分。在传统的引信电路设计中,主要是通过采用各种中小规模集成电路芯片和单片机来设计引信电路。基于FPGA 的激光引信电路充分利用FPGA 的硬件逻辑单元构建各个控制、信号处理模块,实现了引信的高精度和智能化。通过对引信电路进行软件仿真和硬件调试,表明由FPGA 设计的激光引信电路相对于传统的引信设计精度有较大的改善,并提高了电路的可靠性。

Laser fuse is an important part of modern laser homing system.In the traditional fuze circuit design,many fuze circuits were designed by using a variety of small and middle scale integrated circuit chips and microcontrollers.The laser fuze circuit was designed by a piece of FPGA,which makes laser fuze have more accuracy and intelligence by making use of FPGA hardware source design controlling circuit and signal processing module.The fuze circuit based on FPGA was simulated by software tools and debugged with hardware.It was proved that the fuze circuit based on FPGA can improve precision and increase circuit’s feasibility.
