基于FPGA的雷达脉冲信号分选预处理研究

Research into Pretreatment of Radar Pulse Signal Sorting Based on FPGA

对传统的两种雷达信号分选识别算法进行理论介绍,并提出了一种基于现场可编程门阵列的脉冲信号分选方法,通过对脉冲描述字中相邻脉宽的分析处理,实现对雷达信号的简单分选,能够有效缓解后端系统的压力,提高雷达侦察接收机系统的性能。

This paper introduces two radar signal sorting recognition algorithms theoretically, and puts forward a pulse signal sorting method based on field programmable gate array,realizes to sort simply the radar signals through analyzing and processing of the adjacent pulse width in pulse de-scription word,which can effectively alleviate the pressure of back-end system and raise the per-formance of radar reconnaissance receiver system.
