    Abstract

    When an infrared photoelectric detection system detects a target in a complex airborne scene, the spatial distribution of the ground false alarm interference source is consistent with the spatial distribution of the small dim target. Therefore, a multi-dimensional feature association detection algorithm based on moving target features was proposed herein. First, feature points were detected in complex scenes, and a frame skipping mechanism based on the relative velocity-height ratio was introduced. Candidate targets were detected by inter-frame image difference after image registration. Simultaneously, multi-dimension and multi-frame correlations based on the kernel correlation filter were used to suppress false alarms. In an airborne environment where the vehicle speed-to-height ratio is greater than 30 mrad/s and frame time is less than 10 ms, the average detection rate of this algorithm is 99.13%, and the false alarm rate is 10-5. This method was verified in various complex scenarios. In addition, it is suitable for pipeline parallel operation and meets the engineering needs.
