Coherent interference suppression method with virtual array and multi‐stage spatial smoothing

In the presence of coherent interference, adaptive beamforming algorithm fails to form nulls in direction leading cancellation expect signal. To address this issue, paper proposes a interference suppression method with virtual array and multi-stage spatial smoothing (MSS). proposed method, weight acquired by (SS) is applied all subarrays generate array. Another then from using SS another The process iterated until there are insufficient elements for SS. can deeply break correlation between signal deep interference.
