Realization of Laser Pulse Code on FPGA

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 coding and the flow of coding were introduced in detail.The functional simulation and experiment showed that the encoding scheme was feasible.
