摘要
针对民用仿真软件中,动目标飞行器轨迹点错误导致飞行时出现撞山、偏离整体轨迹方向的问题,提出了一种基于前点信息预测纠正动目标轨迹的方法。基于飞行器的最低飞行高度和最大飞行速度,根据飞行器最新轨迹点与前一个轨迹点来判断其位置是否合理,不合理则根据实时速度、航向和两点之间的时间差等参数计算得到测纠正后的最新轨迹点。实验结果表明针对民用飞行器利用该方法,能够纠正预测得到较为合理的、符合整体飞行轨迹的轨迹点。
Aiming at the problem of mountain collison and deviation from the overall trajectory direction caused by the error of the trajectory point of the moving target aircraft in civil simulation software,a method of predicting and correct-ing the trajectory of the moving target based on the information of the previous point is proposed.Based on the lowest flight altitude and maximum flight speed of the aircraft,whether the position of the aircraft is reasonable is judged ac-cording to its latest trajectory point and previous trajectory point.If it is not reasonable,the latest trajectory point after measurement and correction is calculated according to real-time speed,heading,time difference between two points and other parameters.The experimental results show that the predication can be corrected and the trajectory points that are reasonable and consitent with the overall flight trajectory for civil aircraft can be obtained through the method.
