Method for detecting, distinguishing and suppressing cross-eye jamming by single-pulse radar

The invention belongs to the technical field of radar electronic countermeasures, and discloses a method for detecting, distinguishing and suppressing cross-eye jamming by a single-pulse radar. The method is characterized in that two types of angle measuring methods are started to carry out angle measurement again when the single-pulse radar is subjected to the cross-eye jamming and loses a target, whether the cross-eye jamming exists or not is detected through comparing the difference of measured angles acquired by the two types of angle measurements methods, and the cross-eye jamming is suppressed through a method of tracking a jamming source if the jamming exists. The method disclosed by the invention is mainly applied to detecting and suppressing the cross-eye jamming, and influences imposed on the direction finding performance of the single-pulse angle tracking radar by the jamming are eliminated. The method can also be applied to various single-pulse radars or signal detecting, recognizing and tracking devices, thereby quickly recognizing the cross-eye jamming, improving a jamming recognition ability of the system, and effectively resisting the cross-eye jamming.
