We study the problem of parameter estimation in in wideband bistatic MIMO radar system. Firstly, we propose a novel algorithm to estimate Doppler stretch and time delay in fractional Fourier transform (FRFT) domain. Secondly, we also construct two sub-array models based on the peaks of fractional Fourier transform (FRFT) to accurately estimate the direction-of-departure (DOD) and the direction-of-arrival (DOA). Furthermore, the Cramer-Rao bound for parameter estimation is derived and computed in closed form. Parameter estimation performances are evaluated and studied theoretically and via simulations. The simulation results demonstrate that the proposed method can get better estimation accuracy.
