Adaptive clutter-suppression concepts for mobile radars
Abstract
The operating principles of three adaptive moving-target-indication clutter-suppression techniques suitable for airborne radars are explained, and the practical feasibility of the techniques is evaluated by means of numerical simulations. A direct-matrix-inversion (whiten and match) method (1), an auxiliary-channel (match and postwhiten) method (2), and a subgrouping technique (3) representing a compromise between (1) and (2) are examined. Possible hardware implementations are shown in diagrams, and the simulation results are presented graphically. Both of the suboptimal procedures, (2) and (3), are found to be effective in suppressing Doppler-colored clutter, but (2) is considered preferable because it requires much less computation than (3).
