Anti-jamming performance analysis of FDA-MIMO based sidelobe cancellation with Minimum Mean Squared Error algorithm

The frequency diverse array (FDA) introduces the frequency offset between adjacent array elements based on the phased array (PA). Therefore, the FDA has advantages specially for suppressing the jamming at the same angle but different ranges from the target. In this paper, the minimum mean squared error (MMSE) algorithm and the adaptive side lobe cancellation (ASLC) are combined with FDA-MIMO to achieve better performance of suppressing the jamming. Comparing with PA and the FDA-MIMO only with ASLC, the proposed method has better anti-jamming performance. Simulation results verify the effectiveness of the theoretical analysis.
