Abstract :
The relative performance of several well known Doppler processors is examined under a wide range of clutter conditions. Parameters are chosen to reflect land and sea clutter environments, including possible weather clutter components. Performance measures are discussed, with particular attention to filter-bank processing and M/N detection. The improvement factor of each processor and its loss relative to the optimal filter is evaluated in each clutter scenario. The insertion of MTI cancellers before LP or Hsaio filters for dealing with point clutter is discussed. Conventional AMTI and MTI filters are shown to provide dramatically inferior performance in many clutter environments
