摘　　要：针对预警机协同制导应用场景下空空导弹中末制导交接时目标截获概率问题,研究了组合导航误差、导引头波束指向误差、天线罩瞄准线误差、预警机雷达测量误差、目标机动引起的误差和数据传输延迟对角度截获概率、距离截获概率和速度截获概率的影响,提出了目标截获概率的数学计算方法,并给出了一条典型弹道的计算结果。计算分析表明,目标截获概率随雷达测量误差等影响因子增加而降低,其中数据传输延迟对目标截获概率的影响最大,目标横向机动次之;在导弹设计时,为了增加目标截获概率,应优先提高多普勒频率搜索带宽,其次提高允许截获距离和波束宽度。该计算方法方便快捷,不需要建立导弹详细数字仿真系统,可在导弹总体方案设计阶段使用。In order to get the target acquisition probability(TAP)of air-to-air missiles in cooperative guidance scenarios of AWACS easily,the effects of various factors(the errors of INS/GPS integrated navigation system,the error of the phased array antenna beam pointing,the radome boresight error,the measurement errors of the radar of AWACS,the errors caused by maneuvering target,the delay of data transmission,etc.)on the acquisition probability of angle,range and speed are analyzed.A simple and accurate mathematical method for calculation of the TAP is introduced,and the calculation results of TAP for a typical missile trajectory are given.The results show that the TAP reduces as the increase of each impact factor.The delay of data transmission is the most influential factor on the TAP,and the factor of lateral maneuver follows it.In order to increase the TAP,the first priority is to improve the bandwidth of the Doppler frequency detector,and the second priority is to improve the permitted acquisition range and the beam width during missile design process.The method proposed in this paper makes it easy to have the TAP in cooperative guidance scenarios of AWACS without establishing a digital simulation system of air-to-air missile,and it can be used in the conceptual design phase of a new missile.
