摘要: 为了将对瑞利目标的检测与分辨方法应用于多个斯威林4型目标的检测与分辨，该文主要研究了多个斯威林4型目标存在时输出信号近似为高斯分布的条件。首先推导了多个斯威林4型目标存在时雷达接收机输出信号的概率分布；在此基础上，通过仿真获得了输出信号近似为高斯分布的条件，即多个目标中回波功率最大的两个目标的信噪比相差不大于7dB。Abstract: The condition under which the output signals of monopulse radar receiver with two Swerling 4 targets are approximate to the Gaussian distribution has been studied in order to apply the detection and estimation methods of Rayleigh targets to Sweriling 4 targets. First, the probability density function(pdf) of the outputs under multiple Swerling targets are derived; then get the condition, under which the pdf of the outputs is approximate to Gaussian distribution, that the difference between the SNRs of two targets , whose returns power are the biggest among the targets, is not more than 7 dB.
