Paper Abstract

When solar radiation transmits in the atmosphere, radiation wave band from 240nm to 280nm is strongly absorbed by the ozone layer, which makes the ultraviolet radiation in this wave band difficult to reach the near earth surface. It forms the solar radiation blind region on the near earth surface that is usually called solar blind region. Because of the strong absorption, the solar blind ultraviolet detecting system works in wee background noise condition. In this paper, we design a set of ultraviolet detecting experiment system. From the radiometry, we establish an improved estimate of the operating range model based on the target signal, background signal difference and noise of detector. Using the improved model, we can calculate the operating range for point target in solar blind ultraviolet detecting system. For the special ultraviolet target, the calculated values are consistent with the practically measured values in the experiment system designed in the paper.
