Abstract:

Due to the simplicity and low price of chaff,the chaff shell is frequently used in naval battles.Because the chaff shell can interfere with radar effectively,this paper studies the method of distinguishing the target of a fighting ship from Chaff Cloud based on the Spectral expansion effect of the chaff cloud.This method can effectively carry out the purpose of anti-chaff-jamming in naval battles.

Key words: chaff;chaff jamming;spectral expansion effect
