摘要：
To improve the detection performance and detection capture probability of photoelectric detection imaging sensor system in the complex background, which affect and reduce the target detection capture probability, this paper proposes a new target composite detection capture probability calculation model based on the photoelectric detection system of infrared and visible light photoelectric detection sensor. From the target's radiation illumination and background's radiation illumination, we research the relationship between the threshold signal noise ratio and the false alarm probability, set up the false alarm probability function of composite photoelectric detection system, analyze the effect of false alarm probability to target capture probability in photoelectric detection imaging sensor system, and give the relation function of target capture probability and false alarm probability. Through calculation and experiment analysis, the results show that the target capture probability is inversely proportional to background's radiation brightness; While the false alarm probability increases, the target capture probability goes smaller.
