Research on Target Location Method of UAV based on Aided Beacon in Different Field of View

Aiming at the problem that the UAV's single station angle and distance measurement are greatly affected by the UAV's attitude angle error, a method is proposed to solve the UAV's attitude by detecting the auxiliary beacon and combining with the inertial sensor. The attitude solving model of inertial sensor based on CKF is established, by using gradient descent method, the attitude parameters of UAV based on auxiliary beacons are solved, and the results are comprehensively used to estimate and correct the attitude error of UAV, finally the targets' location and simulation calculation under different fields of view are completed. The results show that the method proposed in this paper has improved the precision of UAV target location.
