In order to evaluate the performance of infrared detection system more effectively and evaluate the imaging quality of the system, based on the detection principle of the moving target sequence image and the modeling and simulation technology, the space-based infrared moving target detection simulation system based on matlab platform was designed and developed, Simulation was carried out. The simulation system uses the infrared detection imaging system image as input, and carries on the gray arithmetic and SNR analysis to the image, which reflects the imaging quality of the infrared detection system, realizes single frame detection and multi-frame correlation detection, output detection rate, false alarm rate and the target trajectory, and can evaluate the detection algorithm. The research of detection band and spatial resolution has strong application value in spectrum selection and spatial resolution design of space-based infrared detection system.
