军事训练想定中的三维航迹仿真模型

A Simulative 3D Model of Target's Trail in the Military Training Supposition

将飞行目标的空间机动分段简化为空间恒加速度(或等速)直线机动、空间任意平面内的恒向心加速度圆周机动(包括恒向心加速度水平机动或恒向心加速度垂直机动两个特例),整条航迹就是由若干直线机动段、圆周机动段通过机动点的连接任意组合而成。据此建立了三维空间内的航迹仿真模型,从理论上实现了目标在三维立体空间内的准自由运动仿真,可比较真实地模拟空中目标的各种飞行动作。

On the basis of subsection hypothesis, space maneuverability of flying target was simplified as space constant acceleration (or constant speed) beeline motion and constant centripetal acceleration circumferential motion at any space plane (including two special examples, constant centripetal acceleration level maneuverability and constant centripetal acceleration upright maneuverability). The flight path was composed of some beeline maneuverability section and constant centripetal maneuverability section, which get through the maneuverability point. The 3D space flight path simulation model can simulate any flight action of flight target in 3D space
