中末制导交班是武器导引头工作过程中的重要组成部分。针对地空导弹采用复合制导的特点,首先,推导了导弹角度截获概率与距离截获概率的表达式,着重研究了目标机动对交班成功概率的影响;然后,建立了包含目标落入有效视场概率以及目标检测概率的交接班成功概率模型,可仿真生成任意时刻的交接班成功概率;最后,对水平转弯、蛇形规避两种典型战术机动进行了分析。仿真结果表明隐身飞机采用战术机动对中末制导交班成功概率影响显著。该研究为导引头对抗隐身目标战术机动提供了仿真理论和实验依据。
In the end guidance shift is an important part of the work of weapons seeker. Firstly, the expressions of the probability of interception and the probability of intercept of the missile are deduced. The influence of the target maneuver on the success probability of handover is emphatically studied. Then, the probability that the target falls into the effective field of view As well as the success probability model of transition probability of the target detection probability, which can simulate the success probability of handover at any moment. Finally, two typical tactical maneuvers of horizontal turning and snake avoidance are analyzed. Simulation results show that tactical maneuvers of stealth aircraft have a significant impact on the success probability of mid-last guidance shift. The research provides simulation theory and experimental evidence for the seeker to counter stealth target tactical maneuver.
