Divergence elimination of the extended Kalman filter for target tracking due to Pulse-Doppler radar measurements

Abstract

Extended Kalman filter for target tracking due to Pulse-Doppler radar measurements is often divergent, which is caused by the presence of unaccounted errors which appear in the result of the equation of the range rate measurement linearization. In the article a simple way of the extended Kalman filter divergence elimination is suggested and consists in the variance of value measurement error increase by an amount proportional to the value extrapolation error variance. The coefficient of proportionality is determined by means of statistical modeling by testing the statistical hypothesis of Gaussian distribution of the errors of estimation of the target’s parameters vector. The suggested method analysis is carried out as an example of target tracking due to Pulse-Doppler radar measurements in the Cartesian coordinates using the statistical modeling.
