Abstract

To improve the photoelectric detection capability of optical detection system in near sea surface, this paper set up a photoelectric detection capability model based on solar irradiance and target characteristic, analyzed its optical detection principle and influence factors, researched the target reflection characteristics, the noise characteristics and detection method to calculate the distance in photoelectric sensor detection system. According to the characteristics of solar radiation, the reflection characteristics of the target and the noise characteristics of photoelectric detection system, this paper derived the expression of the maximum detection distance, studied the relationship among the background illumination, aperture of optical system, the effective reflection area and maximum detection distance, concluded and analyzed the changing curves among the aperture of optical system, the light incidence angle and the maximum detection distance, and the changing curves among SNR threshold, the light incidence angle and the maximum detection distance. Through experiments, the results show the established calculation model of the maximum detection distance and analysis method were correct and scientific..
