Multiple targets parameters estimation for bistatic MIMO radar system

In this paper, we present a multiple targets localization and parameter estimation algorithm for a bistatic multiple-input multiple-output (MIMO) radar system. MUSIC estimator is directly employed to estimate the direction of arrivals (DOAs), the amplitude and phase estimator (APES) is used to derive closed-form solution of the direction of departures (DODs), then RCS can be obtained from solutions of DODs and DOAs via least squares method. The DODs and RCS of targets can be solved in close form, and all the parameters are paired automatically. Numerical examples are presented to verify the effectiveness of the proposed method.
