采用现在点射击方式的反舰导弹捕捉概率计算模型

采用前置点射击方式的反舰导弹,在计算射击诸元时,需要目标运动参数,但采用现在点射击方式的反舰导弹,在计算射击诸元时,不测定目标运动要素,不计算导弹自控飞行时间内目标的运动。因此,必须要建立采用现在点射击方式的反舰导弹的捕捉概率计算模型。在把反舰导弹飞向目标过程中的主要误差综合为目标指示精度和侧向偏移两类误差基础上,把目标机动范围、目标指示精度误差作为圆分布来处理,利用解析方法,建立不同误差条件下反舰导弹捕捉概率的计算模型。对高亚声速反舰导弹的捕捉概率进行了仿真,按照捕捉概率的战术标准,得到了对反舰导弹不同发射距离条件下几个参数的要求。

Acquiring Probability Computing Model of Anti-Ship MissileAdopting Present Position Shooting Mode

When anti-ship missile adopts prepositive position shooting mode, the computation of the firing data needs the moving parameter of target. When anti-ship missile adopts present point shooting mode, the computation of the firing data only needs to shoot at target present position without considering target movement and measuring target states during the programmed flight period. Thus, acquiring probability computing model of anti-ship missile adopting present position shooting mode must be established＇. In this paper, based on integrating the main error as target indication precision error and lateral deviation, target maneuvering limit and target indication accuracy error were both considered as circular distribution. By using analytic method, the computing models of the acquiring probability for anti-ship missile on conditions of different error were built. Finally, the acquiring probability of anti-ship missile with high velocity of sound was simulated. According to the tactical standard of acquiring probability, parameter＇s request of anti-ship missile with different launch range was obtained.
