机动目标的三维瞄准火控模型

对新型的航炮攻击数学模型进行了研究,将传统的二维瞄准扩展为三维瞄准;在考虑新一代战斗机机载设备的计算能力大幅度提高的情况下,火控模型引入了加速度因素引起的目标机动项,并给出了目标绝对速度和绝对加速度的计算公式,从而减小了瞄准解算公式的原理误差;通过对复杂的瞄准公式所占用计算时间的估算,证明本文提供的火控模型能够满足实时性要求,具有实用意义。

A Three Dimensional Fire Control Model for a Maneuvering Target

This paper proposes a novel model for three-dimensional air-to-air gunnery targeting. Taking into account of the fact that the modern avionics systems can obtain much more target information, we believe that target acceleration has to be included in any fire control models. Therefore, representations for target inertial velocity and acceleration are provided, leading a considerable reduction in principle errors. Real time computational burder is also estimated, indicating that our model can be implemented in modern airborne computers.
