摘要
脉冲多普勒雷达在工作中受杂波信号的干扰会对检测运动造成负面影响。在多普勒雷达运动时,外部的各种干扰信号会造成多普勒频移产生杂波,杂波为主瓣杂波、旁瓣杂波和高度杂波。为提高脉冲多普勒雷达性能,可以通过测算船舶多普勒雷达的杂波功率,对远处的运动目标进行准确的探测。本文以旁瓣杂波为研究对象,分析了脉冲多普勒雷达系统的构成与特点,论述脉冲多普勒雷达旁瓣杂波分析的模型构建、模型改进与仿真分析。
Pulsed Doppler radar’s interference with clutter signals during its operation will have a negative impact on the detected motion.When Doppler radar moves,various factors from the outside will cause Doppler frequency shift to generate clutter.The clutter is the main lobe clutter,side lobe clutter,and height clutter.In order to improve the performance of pulsed Doppler radar,the distant moving target can be accurately detected according to the clutter power of the ship Doppler radar.This article takes side lobe clutter as the research object,analyzes the structure and characteristics of pulse Doppler radar system,and discusses the model construction,model improvement and simulation analysis of pulse Doppler radar side lobe clutter analysis.
