摘　　要：单脉冲雷达导引头搜索捕捉目标时,如果多个目标存在同一分辨单元内,导引头将难以区分,而无法检测雷达主波束内多个目标的存在就不能进行多目标的分辨,最终无法完成对既定目标的成功打击;采用基于Neyman-Person准则的广义似然比检测(Generalized Likelihood Ratio Test,GLRT)方法可以对单脉冲雷达导引头同一分辨单元内多个Swerling II型目标的存在性进行检测,仿真实验证明了有效性。Monopulse radar seeker will difficultly discriminate multiple targets located in the same resolution cell when the seeker searches and catches the target, and if it can not detect whether there are multiple targets in the main beam of the radar, it is unable to distinguish multiple targets. Ultimately, it can not hit the established goal successfully. Using the Generalized Likelihood Ratio Test （GLRT） method based on the Neyman-Person criterion can detect the existence of multiple Swerling Ⅱ targets in the same resolution cell of monopulse radar seeker, and the simulation results illustrate the good performance of the method.
