A weighted least squares approach for multi-target Doppler-only localization

In this paper a multi target Doppler-only tracking scheme as well as its related algorithms are proposed and analyzed. Specifically the Doppler-only single target localization is firstly addressed in an heteroscedastic environment exploiting a weighted least square approach. Then this approach is extended to a multi target case introducing an algorithm to solve the inherent measurements to targets association problem. Finally the integration of these algorithms with a Kalman filter based tracking stage is analyzed and evaluated through simulations.
