FDA-MIMO Signal Processing for Mainlobe Jammer Suppression

Inspired by the fact that frequency diverse array (FDA) generates a time-variant transmit beampattern depending on both range and angle parameters, we propose joint utilization of the FDA and multiple-input multiple-output (MIMO) radar for counteracting mainlobe jamming signals. In doing so, the advantages of FDA and MIMO in range-time-dependent beampattern and increased degrees-of-freedom, respectively, are combined. The proposed algorithm development is based on eigenvalue projection and blocking matrix processing. Theoretical analysis and simulation results for evaluation of the FDA-MIMO framework are provided.
