Abstract:

The method of clutter suppression and false target elimination in radar data processing is investigated. According to the dense clutter interference and together with engineering practice, a method of clutter suppression based on the clutter map is proposed, and the comprehensive discussion on key technologies is carried on, such as clutter domain discrimination and identification, clutter map grid division, clutter map resolution improvement and so on. Meanwhile, methods of clutter suppression in netted radar data processing are presented, including fusion weight selection in clutter environment for netted radar, clutter suppression and track initialization assisted by information from the fusion center for single radar, etc. Simulation and test results show that the proposed methods can effectively suppress false target track caused by residual clutter and residual interference, and show that the methods are best applied to radar data processing and netted radar data processing in clutter environment.
