针对各类误差和干扰因素在制导炸弹的实际投放过程中客观存在，导致基于理想弹道模型计算出的可达域无法保证必要的命中概率的问题，研究了几种典型误差和干扰对于制导炸弹命中概率的影响。通过综合扰动下的Monte-Carlo仿真打靶实验，从命中概率分布的角度描述了可达域的本质特性。提出了一种可达域的定量缩减方法，有效提高了制导炸弹在实际环境中投放的命中概率。通过仿真可以看出，该方法简明直接，通用性和可行性较强。% Since the objective existence of errors and interference in guided bomb practical delivery process,the accessible region calculated by the ideal trajectory model cannot ensure the necessary hit probability .The influence of some typical errors and interference to the hit probability of guided bomb was studied,the substaintial characteristic of accessible region was described in the view of hit probability distribution via Monte-Carlo target practice simulation in integrated interference .A quantitative reduction method was proposed,which could increase the hit probability of guided bomb in practical delivery environment .Simulation showed that the method is simple and has high generality and feasibility .
