一种基于最小平均距离的测量飞机航迹规划算法

以测量飞机对单个低空飞行器跟踪为研究对象,根据大地坐标系统和椭球几何学基本原理,结合机载测量设备的作用范围,提出一种基于最小平均距离的测量飞机航迹规划算法.分析预定的低空飞行器飞行路线,提取低空飞行器飞行关键点,划分出低空飞行器水平飞行阶段和转弯飞行阶段,按阶段分别规划出测量飞机的航迹,保证对低空飞行器全程连续稳定跟踪的同时,使测量飞机与低空飞行器的平均距离最小,以提高测量质量,并模拟低空飞行器3种飞行路线,规划了相应的测量飞机航迹,经Mat-lab仿真分析,规划结果满足设计要求,验证了算法的有效性.

A Flight Planning Algorithm of TT&C Air Station Based on Minimum Average Distance

During the flight test of one low-altitude aircraft,TT&C air station is able to continuously track the low-altitude aircraft in the whole flight range due to its high height of platform and maneuvering capability.To guarantee continuous tracking of the low-altitude aircraft and minimize the average distance between the air station and the low-altitude aircraft in the whole flight range,an algorithm for flight planning of TI&C air station based on minimum average distance was proposed.The path of the low-altitude aircraft is analyzed,which could be composed by a set of lines and arcs.Simulation results of three tracking examples of the low-altitude aircraft show that the algorithm is effective in solving flight planning problem.
