Abstract

This paper deals with the problem of performance bound for ground moving extended target tracking with high range resolution ground moving target indicator (HRRGMTI). The system model is constructed for our proposed rectangular target tracking. On performance bounds for state and deterministic shape parameter estimation, a hybrid Cramer-Rao lower bound (CRLB) is proposed and its recursive form is derived. By comparison of radicCRLB curves for different accuracies of measurement of down-range-extent, the effect of this additional measurement on state and parameter estimation is analyzed.
