摘　　要：针对弹道导弹突防背景 ,研究了脉冲波形激励下箔条云团的极化散射特性 .导出了任意极化脉冲信号激励下箔条云团的反射场模型 ,给出了其反射场的一、二阶矩 .分析了箔条云团反射场的频谱特性、相关特性及其时频特性 。Based on the background of ballistic missile defense, the polarization scattering properties of chaff cloud illuminated by pulse waveforms are studied. The reflecting model of chaff cloud illuminated by arbitrary polarization pulse signal is derived and one or two moments of its reflecting field are presented. The spectral characteristics, correlated characteristics and time-frequency characteristics of chaff cloud's reflecting field are analyzed. The computer simulation results are given with the spherical uniform distribution chaff cloud.
