Abstract

To improve the detection performance of the infrared detection system, optimize the structure of infrared detection system, this paper studies and analyzes the target surface radiation temperature, infrared radiation characteristics and space target detection distance. Based on the basic principle of the optical imaging detection system, the paper adopts the method of dividing the target into small units to establish a surface radiation temperature calculating model and set up the temperature radiation calculation function, and deduces the detection distance calculation function based on contrast and illuminance. By calculating and simulating, the results show the higher the target’s reflectivity, the brighter the radiance of the target surface in the certain detection distance, and the output signal from photoelectric detector will enlarge..

Keywords
