Airborne Radar Coherent Integration and Sea-Clutter Suppression Method for Marine Moving Target via TSLRT-MFP-SVD.

Airborne radar mainly confronts two problems for marine moving target detection. One the one hand, the relative velocity and acceleration between airborne radar and target cause range cell migration (RCM) and Doppler frequency spread (DFS), degrading the CI performance. On the other hand, heavy sea-clutter influences the focusing/detection results. To solve these problems, this paper proposes a novel fast method based on time slice location rotation transform (TSLRT), matched filtering processing (MFP) and singular value decomposition (SVD), i.e., TSLRT-MFP-SVD. This method combines the ideas of time slices division and echo subspace decomposition to realize valid CI and sea-clutter restrain. Real-data processing prove the validity of the proposed method.
