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.
