Signal modeling of chaff in naval environment simulation

Abstract

With increasing missile processing power, we expect that more elaborate signal processing will be conducted on received target echoes in order to discriminate a real target from a false target. In order to reliably evaluate the effectiveness of chaff recognition algorithms, a model that simulates the Doppler spectrum and the Swerling distribution of a chaff cloud is required.We present a simple assumptions based model that can supply the main spectral characteristics of naval chaff.
