摘　　要：毫米波寻的制导空地导弹可实现“发射后不管”,大幅度提升载机的安全性。不同于其他制导体制,毫米波自寻的需要导引头自主识别和选择目标,难度极大。针对近程毫米波制导空地导弹复杂陆战场环境下的目标选择问题,结合空地导弹的作战使用特点和目标位置信息更新较慢特性,提出了一种基于观测匹配的毫米波导引头目标选择方法。由弹上计算机存储基于火控信息解算出的威胁目标位置信息;导弹飞行过程中,弹上计算机实时计算毫米波导引头的目标指向信息,以提高导引头开机时捕获目标的概率;进入毫米波导引头的有效作用距离后,毫米波导引头开始扫描探测目标,捕获目标后,实时解算目标位置信息;对比判定目标位置信息是否与火控解算信息相匹配,实现毫米波导引头对威胁目标的准确选择。实测数据验证了所提方法的有效性。The MMW homing guided air-to-ground missile can realize"fire and forget",improving the safety of the carrier dramatically.Different from other guided systems,the MMW seeker needs to identify and select the interested targets independently,which is extremely challenging.Focusing on the problem of target selection under complex land battlefield,a method using tracking preserving is proposed,which takes the characteristic of missile usage and slow changing property of the target position into consideration.Target position obtained by the fire control system is stored by the missile-borne computer.Target pointing of the MMW seeker is calculated in real time during the missile flight to improve target capturing probability.The MMW seeker starts to detect the target when the distance between the seeker and the target is less than the seeker’s effective working range.Target position will be calculated when the seeker captures the target.Target positions obtained by the seeker will be compared to the ones obtained from the fire-control system,realizing accurate selection of the threatening target.Real collected data have verified the effectiveness of the proposed method.
