In order to meet the requirements of radar seeker tracking with high dynamic and high precision, a bounded positive correlation adaptive tracking control algorithm is proposed. By analyzing the mutual restriction relationship between the indexes, an adaptive tracking controller is constructed, in which the integral coefficient is positively correlated with the change of tracking angle error. The fitting calculation of the adaptive integral coefficient polynomial of the controller considers the requirements of isolation index, tracking distance mode and maximum tracking angle velocity accuracy. The experimental results show that when tracking 10 (°)/s target, the line-of-sight angular velocity accuracy is improved by more than one time, while meeting the requirements of the isolation index.
