Abstract

As an important method to protect airplane from attacking from missiles,chaff centroid jamming plays an important role.Provided that the chaff cloud is sphere and chaffs distribute uniformly in it,a numerical calculation method was presented to calculate the reduction of RCS of chaff cloud due to the effect of incising,and a new method was given to simulate the dynamic course based on modeling of chaff cloud,aircraft,missile and beam.With this method,the impact of the optional throwing angles and diffusing velocity of chaff cloud on the effect of jamming were analyzed.
