箔条云回波的一种建模与仿真方法

A Modeling and Simulation Method of Chaff Cloud Echo

为了检验箔条干扰的性能以及研究抗箔条干扰的效果,根据箔条回波的时频分布和统计特性,提出了一种基于其产生机理的箔条回波信号的建模与仿真方法。仿真结果表明,该方法产生的箔条回波信号与箔条实际回波的各项分布特性相同,从而证明了该方法的正确性。

In order to verify the effect of chaff- jamming and study the effect of anti-chaff-jamming, according to the timefrequency distribution and statistic characteristics of chaff echo, this paper presents a modeling and simulation method of chaff echo based on its mechanism of generation. The simulation results indicate that the generated chaff echo of this method has the same dis- tributions of the actual chaff echo. Thus it proves the correctness of this method.
