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 return’s power are the biggest among the targets, is not more than 7 dB.
