Joint MIMO and Frequency Diverse Array for Suppressing Mainlobe Interferences

This paper jointly exploits multiple-input multiple-output (MIMO) increased degrees-of-freedom and frequency diverse array (FDA) range-dependent beampattern to suppress mainlobe interferences. The interferences caused by deceptive or false targets are separated firstly in the range dimension with blocking matrix method, and then the true target is estimated with the eigen-projection matrix preprocessing. All proposed methods are verified by simulation results.
