In order to reduce the influence of fast moving jamming signal and desired signal steering vector mismatch onradar performance, a robust joint transmit-receive beampattern design method for multiple-input multiple-output (MIMO) radarunder jamming environment is proposed. By designing the joint transmit-receive beampattern of MIMO radar, not only the jammingsignal can be effectively suppressed, but also the desired signal cancellation phenomenon can be avoided. Experiment resultsdemonstrate the validity of the proposed method.
