摘要
针对存在于某型激光制导炸弹导引过程中的若干误差源,建立了各自的数学模型,给出了一种导引精度描述模型。在此基础上采用统计试验法通过计算机六自由度全弹道仿真,评估了各种误差作用下的导引精度,并对仿真结果进行了分析。仿真试验表明航弹在典型投弹条件下能够满足导引精度设计指标。
Aim. In order to improve the precision of laser guidance, it is necessary, in our opinion, to analyze the degrading effects of various factors on precision of laser guidance of a certain type of aerial bomb. We now present our simulation research results on such degrading effects with a view to improving the precision of a certain type of laser guided aerial bomb. In the full paper, we explain in detail our simulation research results; in this abstract, we just add some pertinent remarks to listing the two topics of explanation： （1） the mathematical model of various factors influencing guidance precision; （2） the method of calculation; the subtopics of topic 1 are the characteristis of laser guidance（subtopic 1.1）, the effect of imperfect bomb release （subtopic 1. 2）, the effect of the vicissitudes of flow field on aircraft （subtopic 1.3）, and the effect of imperfect laser tracking of target（subtopic 1.4） ; under topic 1, we derive eqs. （1） through （7） in the full paper; under topic 2, we derive eq. （8） in the full paper. Table 1 in the full paper gives numerical simulation results for a certain type of aerial bomb. Such simulation already took into consideration the degrading effects of the above-mentioned four factors. The results indicate preliminarily that this type of aerial bomb as originally designed can satisfy the design requirements on precision under typical release conditions.
