Abstract
This paper proposes a novel method based on wide-band ambiguity function in Wideband bistatic multiple input multiple output (MIMO) Radar System. Firstly, Doppler stretch and time delay are jointly estimated by peak searching the wide-band ambiguity function (WBAF). Secondly, two sub-array models are constructed based on the WBAF. Furthermore, two modified algorithms are proposed for the estimation of DODs and DOAs, including the wide-band ambiguity function based on MUSIC algorithm (WBAF-MUSIC) and the wide-band ambiguity function based on ESPRIT algorithm (WBAF-ESPRIT). Simulation results are presented to verify the effectiveness of the proposed method.
