摘    要:研究多重脉冲重复频率体制的脉冲多普勒雷达,利用余差查表法解多目标距离模糊的问题.对于一个四重脉冲重复频率的雷达系统,利用真实目标在任何两个脉冲重复频率上检测得到的视在距离,经过余差查表法匹配解得的目标距离是相同的这一特性,可以对多目标进行解距离模糊.提出的基于余差查表法的算法,可以有效地对多目标环境进行求解.尤其是在目标个数较少、系统设计脉冲重复频率选择合适的情况下更为有效.

关 键 词:多目标  距离模糊  解模糊  余差查表法

Abstract:Discusses methods for the resolution of ambiguity of multiple tragets using residues' difference look up table, in a pulse Doppler radar working in a four PRFs system. For a four PRFs' radar system, the resolved results calculated by the residues' difference look up table method from any two of the target distances detected are equal. With this the ambiguity of multiple targets can be resolved. The method based on residues' difference look up table as presented in the paper can resolve the ambiguity of multiple targets correctly, especially when the number of targets are few and the system design is well done in choosing appropriate PRFs.
Keywords:multiple targets  range ambiguity  resolving of ambiguity  residues' difference look  up table method
