| 摘 要： | 为实现激光制导炸全弹道弹捕获域的快速计算,首先通过对激光导引头捕获目标条件分析,以目标为中心建立了激光制导炸弹瞬时捕获域模型并给出了瞬时捕获域的形状及决定因素,在此基础上,提出了激光制导炸弹全弹道捕获域的计算方法。其次以制导炸弹飞行弹道倾角不变为假设,给出了采用平台导引头和捷联导引头激光制导炸弹的全弹道捕获域理论表达式。最后,对采用不同制导律的激光制导炸弹捕获域理论计算值与仿真值进行了对比,结果表明:捕获域理论表达式计算结果与弹道仿真结果基本吻合,可用于激光制导炸弹捕获域的快速解算。

| Abstract: | To achieve the rapid calculation of the laser guided bomb's total capture area, based on the principles of capture target of laser seeker, taking the target point as center, the instant capture area model was established and the shape of instant capture area and its deciding factor were analyzed. On this basis, the calculation method of total capture area of laser guided bomb was proposed. Secondly, under the assumption of flight path angle keeping constant, the total capture area's theoretical expressions of guided bomb with gimbaled seeker or strapdown seeker were put forward. Finally, the results of total capture area of laser guided bomb guided by proportional navigation guidance and trajectory shaping guidance calculated through theoretical expression and computer simulation were contrasted. The results show that the expression's result matches the simulation and the theoretical expression can be used on fast calculation of laser guided bomb's total capture area. |
