In this paper, the authors propose a novel wideband signal model and a novel method in wideband bistatic multiple-input multiple-output radar system. It combines the Fractional Lower Order Statistics and Fractional Correlation (FLOS-FC), for suppressing the impulse noise and estimating parameters of the target. Firstly, an extended signal array model is proposed under the alpha-stable distribution noise model. Secondly, Doppler stretch and time delay are jointly estimated by searching the optimal rotation angle to meet concentrated-energy of the FLOS-FC.
