摘要:

提出了一种旨在提高定位精度,同时具有保证通信距离约束和传感器探测距离约束性能的无人机双机协同跟踪路径规划算法。分析了传感器误差引起的目标定位误差,指出使用协同跟踪的优势。针对通信约束、传感器距离约束以及精度要求,分别提出了漏斗函数、参数冻结等策略,满足了双无人机协同目标跟踪时的相关约束。设计了双无人机目标三维定位的方法。通过对无人机双机协同跟踪精度与单机目标测量精度仿真对比,验证了算法能够在维持两种距离约束的情况下,以较高的精度跟踪目标。

Abstract:

A kind of unmanned aerial vehicles (UAVs) cooperative ground targettracking pathplanning algorithm is proposed, and this algorithm guarantees that the communication range constraints between two UAVs〖JP〗 and the detection constraints of the UAV’s sensor are satisfied. Beginning with a formulary analysis of the reason for tracking errors, the benefit of cooperative tracking is manifested. Concerning the communication range constraints, sensor constraints and accuracy requirement, corresponding solutions are constructed in the following. In order to assess the tracking procedure, a cooperative 3D target positioning method is proposed. With respect to the tracking accuracy, simulation against noncooperative methods is performed and the range maintaining ability as well as the accurate performance is verified in this analogous way.
