    • Abstract
  • Airborne infrared measurement systems are mounted on aircraft to track and measure the infrared characteristics of the ground target. The impact of platform jitter and environmental change must be addressed to achieve stable tracking and measurement accuracy. To this end, the technology of passive isolation and active gyroscopic stability control was used in this study to examine the influence of airborne platform jitter. To ensure stable tracking and imaging, the high-frequency disturbances were isolated through a passive shock absorber, and the low-frequency disturbances were suppressed through a frame servo system. Non-thermalization compensation calculation and focusing compensation control were adopted in the design of the optical lens to ensure clear imaging of the equipment and thus study the influence of the temperature change of the ground and air environment on the infrared optical system. Simulation calculations and field measurement demonstrated that these vibration reduction measures are reasonable and effective. The equipment thus developed is stable in tracking and clear in imaging. Therefore, it is suitable for realizing hanging flight measurement on different platforms.
