基于时间逐次逼近法的舰载直升机归航航迹研究

Research on the Homing Track of Carrier-Helicopter Based on Time Gradual Approach Algorithm

在明确舰、机位置及母舰运行计划的情况下，基于肓棋坐标系统、大地圆弧航线解算及时间逐次逼近算法的基础上，文中对远程执行任务的舰载直升机航迹进行了研究，并推导了求解最佳归航子空域的通式。仿真验证了算法的准确性。

On the condition that the position of carrier-helicopter and ship and the latter＇s navigation plan were known, and based on blind-chess coordinate system, the earth arc-course algorithm and time gradual approach algorithm, the track of the carrier-helicopter that carrying out task distantly was studied, and the consistent formula for the calculation of optimal homing sub-airspace was deduced. The simulation validated the veracily of the algorithm.
