摘要:

针对空中运动目标参数的实时解算和定位精度问题,基于运动多站无源定位技术,设计了空基分布式定位系统,利用测向交叉定位原理建立了双机协同被动定位模型。模型中完成信息保障任务战斗机的存在使得目标定位误差迅速最小化。通过动态规划法进行双机航迹控制算法设计。使用带有线性策略的共轭梯度法解算信息保障机的最优航迹。仿真表明,该控制算法可以得到信息保障机的最优航迹,双探测端分布式定位系统通过航迹优化,实现了对目标的快速高精度定位。

Abstract:

For the realtime air moving target parameters and positioning accuracy problem, based on the passive location of multiple moving observers, the air distributed positioning system is designed, the aircraft collaborative passive positioning model is established by using the directing of arrival double theory. The existence of the information security task fighter in the model minimizes target positioning error quickly. Through the dynamic programming, the double aircraft track control algorithm is designed. Use the conjugate gradient method with the linear strategy to calculate the optimal information security machine. Simulation shows that the optimal path of the information security aircraft can be got by using the control algorithm. The double detection distributed positioning system after trajectory optimization can rapidly achieve high precision positioning of the target.
