| 摘 要： | 激光脉冲编码作为半主动激光制导武器提高抗干扰性的重要手段,主要是通过增加编码位数和脉冲间隔时间值的方法实现。本文分析了激光脉冲编码的特点,提出一种基于FPGA利用verilog硬件编程语言实现的编码位数和脉冲间隔均可调的周期脉冲间隔编码设计方案;对该编码方案的硬件结构和编码流程作了详细的介绍;通过功能仿真和实验测试证明了该编码方案的可行性。

| Abstract: | Laser pulse coding is considered as the most important means to enhance anti-jamming of self-active laser homing weapons,it is achieved mainly by increasing the coding bits and coding pulse interval.The characteristics of the laser pulse coding were analyzed in this paper.Based on that,a coding design,using a hardware language called verilog implemented on the FPGA for the system of laser pulse coding was proposed,in which the coding bits and coding pulse interval could be adjusted.The hardware structure of... |
