Abstract An algorithm combined MUSIC with ESPRIT for angle estimation based on two- or four-order statistics in bistatic MIMO radar system is presented in this paper. The proposed method based on two-order expectation is under the spatial Gaussian white noise environment and four-order cumulant the colored noise. By exploiting MUSIC with one-sensor owing to its extended array aperture and ESPRIT with two-sensor via the rotational invariance property of signal-subspace at the receive end, the Direction Of Departures (DODs) and Direction Of Arrivals (DOAs) of the targets can be estimated separately and paired automatically. The computational burden can be reduced since two-dimensional parameter estimation has been separated into two one-dimensional forms. Numerical results are presented to demonstrate the effectiveness of the method advanced.
