A Modeling and Simulation Method of Chaff Cloud Echo

In order to verify the effect of chaff-jamming and study the effect of anti-chaff-jamming,according to the time-frequency 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 distributions of the actual chaff echo.Thus it proves the correctness of this method.
