In this paper a novel scheme for anti-ship missile radar seeker is proposed. The theoretical basis of the scheme is the obvious difference in the depolarization between the warship and the chaff cloud. In order to examine the properties of the scheme, the depolarization characteristics of the chaff cloud are firstly analysed. Particularly, the depolarization factor is defined and its probability density is deduced. Thereby, a maximum likelihood detection system to identify chaff interference from naval vessels provided and its error detection probability is calculated. Finally, several measuresto reduce the error detection probability are discussed. The results show that the sequential detection method is a better one to settle the contradiction between enhancing identifying performance and shortening observation time.
