介绍一种导引从突防飞机上发射的空空导弹攻击装有搜索雷达的目标飞机的方法。一旦导弹被探测，目标飞机的搜索雷达立即关机，导弹由反辐射寻的方式转为主动搜索方式。这种主动寻的头利用窥视目标飞机的合成孔径雷达。在目标飞机搜索雷达关闭时的这一转换时刻，导弹转弯离开目标飞机并把它引入合成孔径雷达的搜索范围内。转弯量在基于几个参数计算得到的极限范围内。 A method of attacking a target aircraft equipped with a search radar by directing an air-to-air missile launched from a penetration plane to be introduced. Once the missile is detected, the search radar of the target aircraft is shut down immediately, and the missile is changed from active search to passive search. This kind of active looking head uses a synthetic aperture radar that looks into the target aircraft. At this transitional moment when the target aircraft search radar is off, the missile turns away from the target aircraft and directs it into the search range of synthetic aperture radar. The turn amount is within the limit calculated based on several parameters.
