摘　　要：针对射后截获成像制导模式一次捕获概率问题,利用光学成像的规律,将捕获概率考虑为自控段误差相对导引头视场的正态分布,建立了基于自控段误差、目标大小、导引头分辨率的一次捕获概率估算模型。将自控段误差分解为目指系统误差、导引头误差和导航误差,在假定前两者一定的情况下,计算了捕获概率与导航误差的关系,提出了两种可放宽导航误差指标的解决方法。仿真结果表明,在相同一次捕获概率的情况下,所采用的方法可放宽导航误差指标近两倍。Aiming at the question of one-time capturing probability under the mode of after-launching- capturing image guidance, a capturing probability model considering error of self-control section, target size and resolution of the seeker is given out, which using the optics image law and considering the self- control section error against field of seeker as the normal distribution. The self-control section error is decomposed into target detecting error, seeker error and navigation error. The relation between capturing probability and navigation error is calculated when supposed the constant of target detecting error and seeker error. And then, two methods of relaxing navigation error quota are given out. Simulation results indicate that these methods can relax navigation error quota by nearly two times when under the same capturing probability.
