Estimation of the micro-motion parameters of a missile warhead using a micro-Doppler profile

Abstract

This paper deals with the problem of estimating micro-motion parameters. The proposed algorithm uses independent-component analysis to decompose the received signals into individual scatterer signals, and uses particle-swarm optimization to estimate the micro-motion parameters in a micro-Doppler profile. Simulation results show that the proposed method can successfully estimate micro-motion parameters of a warhead model consisting of many point scatterers.
