| description | The invention provides a method for identifying range ambiguity and azimuth ambiguity of a ring-scan radar, and the method comprises the steps: building a position and energy corresponding model of arange ambiguity target and a real target of the ring-scan radar, and identifying whether a to-be-outputted target is a range ambiguity false alarm or not; whether a to-be-output target is an azimuth fuzzy false alarm is identified by establishing a position and energy corresponding model of a loop sweep radar azimuth fuzzy target and a real target, and if the target is a false alarm caused by thetwo kinds of fuzziness, the false alarm is eliminated, so that the false alarm rate of the system is reduced, and the confidence of radar detection of the target is enhanced.
本发明提出环扫雷达距离模糊和方位模糊鉴别方法，通过建立环扫雷达距离模糊目标与真实目标的位置及能量对应模型，对待输出目标是否是距离模糊虚警进行鉴别；通过建立环扫雷达方位模糊目标与真实目标的位置及能量对应模型，对待输出目标是否是方位模糊虚警进行鉴别。若目标是由于这两种模糊造成的虚警，则予以剔除，以降低系统虚警率，增强雷达检测目标的置信度。 |
