technical field [0001] The invention relates to a deep-space infrared point target imaging simulation method, in particular to a deep-space infrared point target imaging simulation method based on semi-physical objects. Background technique [0002] Infrared point target detection is an important part of verifying the capabilities of deep space infrared detection and early warning systems. Usually, in order to verify the system's ability to detect point targets, half-in-the-loop simulation is used to generate a sequence of infrared point target images. In the existing simulation method, the simulation of the background and the characteristics of the imager by the digital scene simulator of the infrared point target cannot accurately reflect the characteristics of the actual system, such as the noise distribution in the time domain and the air domain, the characteristics and distribution of the detector's bad elements, etc., resulting in inaccurate simulation results Demonstr...
