DOA Estimation of MIMO Radar System Based on Cyclic Statistics

Artificial signals possess some certain chronological property-the cyclostationarity, with which the traditional DOA estimation can rarely reach the desired precision, or completely turns to be of no avail. Designated for removing the defect, this paper applies the Cyclic-Music algorithm to the MIMO radar's DOA estimation and verifies its effectiveness. Simulations show that the precision of MIMO radar's DOA estimation, equipped with the Cyclic-Music algorithm, is to a great extent improved, in the context of cyclostationary signals.
