为了提高高炮火控系统的射击精度,针对高炮火控系统中的数学模型问题,对高炮火控系统中的滤波方法、预测模型进行了深入研究并对高炮射击命中概率的影响进行了简要分析。找出现行高炮火控系统中滤波方法和预测模型对机动目标命中概率低的原因。通过对机动目标(飞机)俯冲航路的特点以及被保卫目标的信息进行分析,提出一套针对飞机俯冲攻击的数学模型,有效解决了命中概率低的问题。利用靶场飞行试验航路数据对数学模型进行了验算。结果表明:该方法能减小计算高炮射击诸元的系统误差,提高对飞机未来点预测的准确性,对提高高炮火控系统的射击精度具有一定的意义。

To improve the firing precision of the antiaircraft gun fire control system, aiming at the math model problem of antiaircraft gun firing control system, the filter method and predication model method are researched and the influence of hitting target probability in the antiaircraft gun fire control system is analyzed. Find out the reason of low hitting target probability of filter method and predication model to mobile target. Through analyze dive track features of mobile target （aircraft） and guard target information, put forward the math model of aircraft dive attack, solve the low hitting target probability effectively. Use shooting range flight track data to verify the math model. The result shows that the method can decrease system error and improve predication accuracy to aircraft future point. It is useful to improvement of firing accuracy of antiaircraft gun firing control system.
