摘要
高技术条件下的空中对抗,为了能够对敌方目标的航迹和状态进行有效预测,需要对其三维航迹进行分析与仿真。国内外对目标航迹进行分析与模拟时,多数将其看成简单的直线运动或圆周运动及其组合,未考虑其它复杂情况,也未将速度变化纳入航迹分析中。根据空中飞行目标运动的实际情况,将椭圆弧航迹与复杂航迹引入航迹分析与模拟中,并将航迹归为四类:直线航迹、水平面内弧线航迹、铅垂面内弧线航迹和复杂航迹。通过对四类航迹进行分析,建立各类航迹的数学模型,并对模型进行仿真,仿真达到预期的效果。
In order to predict the tracks and states of enemy flight targets effectively in aerial confrontation under high-tech conditions,we need to analysis and simulate the three-dimensional tracks of the flight target.The target tracks are usually considered as simple linear motion and circular motion and their combination in the target track analysis and simulation at home and abroad.No other circumstances are considered in the track analysis.When considering the actual situation of the movement of the flight target,the elliptical arc track and the irregular track are used in the target track analysis and simulation.And the flight tracks are classified into four categories:linear track,arc track in horizontal plane,arc track in lead vertical surface and complex track.Analyzes four kinds of tracks and builds their math models,simulates the models and achieves the desired effects.
