Abstract

Abstract

For the problem of signal interception and fast moving jammers in MIMO radar application, this paper designs a new transmit beampattern through optimizing the transmit beamforming matrix based on the minimization of integrated-sidelobe. This new transmit beampattern can not only focus the transmit energy on the desired spatial sector but decrease the level of sidelobe as well as form a nulling at the jammers direction with the prior knowledge. At the receiving, a new robust beamforming method based on non-uniform generalized diagonal loading is proposed, which can strengthen the robustness of receiving beamformer against different errors and broaden the nulling adaptively. Through the optimization of joint transmit and receive beampattern for MIMO radar, the interception of signal and fast moving jamming are addressed, which improve the performance of MIMO radar from both transmitting and receiving. Simulation results and comparisons with existing methods demonstrate the feasibility and effectiveness of the proposed methods.
