摘要

在广泛的杂波条件下，研究了几种著名的多普勒处理器的相对性能。所选择的参数反映陆地和海洋杂波环境，包括可能的天气杂波成分。讨论了性能措施，特别关注滤波器组处理和M/N检测。在各种杂波情况下，评估了每个处理器的改进因子及其相对于最优滤波器的损耗。讨论了在LP或Hsaio滤波器前插入MTI消去器处理点杂波的方法。传统的AMTI和MTI滤波器在许多杂波环境中显示出明显较差的性能。

A comparison of conventional, adaptive and hybrid Doppler processing techniques

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.<>
