摘要
针对攻击区对载机火控设备提出的实时性和精确性要求,提出一种分段拟合攻击区的算法。首先对求解攻击区的仿真拟合法和快速模拟法进行简单分析和比较,提出分段拟合的算法思想;然后建立攻击区数学模型,结合多元回归理论对分段拟合方法进行详细介绍,并利用该方法对制导炸弹攻击区进行分段拟合,对拟合系数进行了回归检验;最后将分段与不分段两种拟合结果进行比较,结果表明,分段拟合效果较好。
Considering the requirements to the airborne fire control system on real-time and precision performance for attack envelope calculation, a segmented fitting attack envelope algorithm was proposed. Firstly, two kinds of method for calculating the attack envelope were introduced and analyzed, based on which the segmented fitting method was proposed. Then, a mathematical model of the attack envelope was built up, and the method was introduced in detail based on theory of multiple regression. The method was used for segmented fitting of the guided bomb attack envelope, and the regression coefficient was checked by regression examination. Finally, the result of segmented fitting was compared with that of the non-segmented fitting, and the result showed that former is more efficient.
