N2 - The lower error bounds for Doppler-based localization are investigated. The observer is a sensor platform with several identical sensors. They are aligned as a uniform linear array (ULA). Two cases are analyzed: Firstly, the case of constant velocity (CV) of the target and, secondly, the case of constant acceleration (CA). In both cases, we consider an approaching target which moves towards the ULA. The knowledge about the true initial target state is uncertain. As an indicator of best possible tracking performance, the theoretical Cramer-Rao bounds with respect to the estimation accuracy of recursive filtering are investigated. The simulation results indicate good tracking capability for a 24 GHz radar system, even for the case of only two sensors, and, for more than three sensors, a gradual saturation effect.
