研究了雷达导引头的交班误差以及截获概率与交班时刻弹目几何位置的关系 ,提出了单个误差角的导引头天线指向角误差模型 ,它与两个误差角的导引头指向角误差模型相比可以更好地分析天线指向角误差 ,并得到使指向角误差最小的弹目几何位置 ;然后进一步得到使多普勒频率误差最小的弹目几何位置 ;给出了最终的截获概率的表达式 ,截获概率由目标处于导引头天线主波束的概率、目标回波多普勒频率落入接收机频带内的概率和目标的检测概率组成的 ;最后分析了一种典型的中末交班情况 .
The relationship between the handover error of the radar seeker and the interception probability and the geometrical position of the projectile at the time of handover is studied. An error angle model of the seeker angle of the seeker with a single error angle is proposed, which is related to the error of the steering angle of the seeker Compared with the model, the error of the antenna pointing angle can be better analyzed and the projectile geometric position with the smallest error of the steering angle can be obtained. Then the projectile geometry position with the smallest error of the Doppler frequency can be obtained. Finally, The probability of the expression and the intercepting probability consists of the probability that the target is in the main beam of the seeker antenna, the probability that the target echo Doppler frequency falls into the receiver band and the detection probability of the target. Finally, a typical case of end-to-end handover .
