Robust beampattern design for MIMO radar based on the first null constraint

In this letter, a transmit waveform covariance matrix design method based on the first null constraint is proposed for the transmit beampattern design of Multiple-Input Multiple-Output radar.This method effectively concentrates more transmit energy within the beam, thereby enhancing the detection capability of radar.Additionally, considering the presence of steering vector errors in the radar transmit array, a robust waveform design method under the same constraint is also proposed.Finally, simulation experiments demonstrate the effectiveness of the proposed method.
