In order to improve the accuracy of UAV ground target tracking and positioning, the UAV optoelectronic imaging platform was used to lock the target in the center of the field of view. According to the coordinate transformation, the angle of view was converted to the angle in the geographic coordinate system, and the target tracking System equations was established. Unscented Kalman filter was used to solve the non-linear estimation of tracking and positioning. Due to the problems of slow tracking speed and divergence, iterative non-unscrambled Kalman filter was used to determine the iteration condition by maximum likelihood estimation method, which increases the accuracy and time of filtering. Simulation analysis shows that iterative unscented Kalman filter can significantly improve the accuracy of filtering and the speed of filtering, which has certain practical value.
