Abstract

The paper deals with state estimation for the track-before-detect approach using the particle lter. The focus is aimed at the track initiation proposal density of the particle lter which considerably affects estimate quality. The goal of the paper is to design a proposal based on a Gaussian mixture using a bank of extended Kalman lters. This leads to root mean square error lower than that achieved by usual simple track initiation proposals. Due to application of several developed techniques reducing computational requirements of the designed proposal, the Gaussian mixture particle lter also achieves lower computational requirements than ordinary particle lter. Performance of the proposed Gaussian mixture track initiation proposal in the particle lter is demonstrated in a numerical example.
