Two-stage localization method in multistatic radar systems

In this paper, we present a new localization method in multistatic radar systems. Based on two-stage algorithm, which is used to estimate the location of a target that transmits a signal in passive sensor networks, we reformulate the target localization problem and derive the new two-stage algorithm which suits our situation. Simulation results demonstrate that the proposed method outperforms conventional methods and achieves the Cramer-Rao lower bound (CRLB) with the knowledge of noise statistics over the range of moderate noise power.
