摘要
针对限定虚假目标航迹条件下,搜索法对于无人机组模型的建立以及求解难度都较大的问题,采用分段拟合的思想来求解无人机组的运动规律和协同策略。首先,建立了曲率分段准则,对虚假目标航迹进行合理分段;其次,在每段上建立无人机运动参数方程,利用无人机、雷达、虚假目标航迹三者共线特性得到冗余线性方程组,采用最小二乘法拟合法,建立目标优化函数;最后通过凸优化方法进行求解,得出无人机的运动轨迹参数方程。实验结果验证了该方法的合理性及实用性。
For the problem that the search method is difficult to build and solve the multi-UAVs model under the condition of limited phantom track,the idea of piecewise fitting is used to solve the multi-UAVs'motion law and coordination strategy.Firstly,the curvature segmentation criterion is established to segment the phantom track reasonably.Secondly,the motion parameter equa tion of UAV is established on each segment,and the collinear characteristics of the drone,radar and phantom track are obtained.The redundant linear equations are solved by the least squares fitting method to establish the target optimization function.Finally,the convex optimization method is used to solve the equations of the trajectory of the UAV.The experimental results verify the ratio nality and practicability of the method.
