无人机纯方位无源定位问题研究
Research on azimuth-only passive location of UAVS
摘要
Abstract
Unmanned Aerial Vehicle(UAV)has become critical equipment of modern air combat with the characteristics of excellent concealment,high safety and strong anti-interference.However,existing passive positioning models for UAV often suffer from significant positioning deviations.In order to solve this problem,based on the geometric relationship of UAV formation position,a nonlinear mathematical model of bearing-only passive location is established,and applies to the precise positioning of UAV in the case of circular formation and conical formation.The research results show that when the transmitting UAV's identity is known,the established mathematical model for precise positioning angle is feasible,providing explicit analytical solutions for the coordinates of other UAVs.When the identity of the transmitting UAV is unknown,the established positioning model based on nonlinear equations is effective.The Newton iteration method is used to solve the precise position of the UAV transmitting the signal,so as to solve the position deviation problem of other UAVs.Finally,the experimental results show that the proposed model is reasonable and effective.关键词
