Stable gaze scanning control technology is the key to realize the integration of stable imaging, search, and tracking on airborne platforms. We investigate the control technology of stable gaze scanning on an airborne platform. The working principle of a stable staring scanning system is analyzed, and a servo system control algorithm is modeled. The position loop, velocity loop, and acceleration loop are designed. A stability model of the space with inclination angle is established. The coordinate transformation relationship between inertial coordinate system and airborne axis coordinate system is obtained. The designed control model and algorithm are used to control the single-lens reflex mirror mounted at an angle of 15 deg for spatial gaze pointing and step scanning. A test system is built for performance verification. Results show that the root-mean-square accuracy of the proposed algorithm is higher than 10  μrad in a dynamic staring step scan with ±30  deg and a step length of 2.16 deg. The single-step time is <52  ms, the stabilization time is >53  ms, and the servo system overshoot is small. The system step accuracy root mean square is better than 52  μrad. These findings confirm the effectiveness of the integrated search and follow technology under an airborne platform.
