摘　　要：杂波的处理能力将直接关系到雷达对目标的识别与跟踪效果,因而一直成为国内外学者共同关注的问题。当前,基于杂波统计特征的参数化处理方法常无法对处于强杂波环境内的弱小目标进行有效探测,也无法对具有不同分布特征的杂波进行高效处理。而非参数化的处理没有充分利用扰动的先验信息,因此尽管自适应能力很强,但针对性不强。研究更加高效的雷达杂波预处理技术,并在此基础上提出了一种新的方法。The ability of clutter processing will be directly related to the target recognition and tracking effect of radars,so it has always been a common concern of scholars at home and abroad. At present, the parameterized processingmethod based on the statistical characteristics of clutter can not effectively detect small and weak targets in thestrong clutter environment, nor can it efficiently process clutter with different distribution characteristics. The nonparameterizedprocessing method does not make full use of the prior information of disturbance, so it has very strongadaptive ability but poor pertinence. Therefore, a more efficient method of radar clutter preprocessing is studied, anda new method is proposed.
