Advances and Perspectives in Radar ECCM Techniques of Active Jamming

Radar active jamming brings a huge challenge for radar target detection, tracking and identification. This makes the development of radar electronic counter-counter measurements(ECCM) against active jamming urgent. The ECCM techniques concern about every procedure of Radar. This paper reviews the ECCM techniques including system design, waveform design, antenna design, signal processing and data processing. The latest developments of relative algorithms are discussed, and several major problems as well as the existing obstacles in Radar ECCM are introduced. The performance evaluation methods and their shortage are also briefly introduced. The feasible solutions to overcome these obstacles are given accordingly. In the end, the perspective and application of radar ECCM against active jamming are proposed.
