The solar blind region provides a good background for the detection systems that work in the wavelength from 240 to 280 nanometers on the near earth surface. A set of solar blind ultraviolet imaging detection experiment system is proposed. From the point of view of radiation energy transfer, referring to the analysis methods of staring infrared search and track system, the detection range model of ultraviolet detection system was derived. With a deuterium lamp as the detection target, the experiment system and model were analyzed and validated in experiment under conditions of three kinds of typical weather. The result suggests that the calculated values are consistent with the practically measured values.It provides an important theoretical and experimental basis for the design and performance evaluation of solar blind ultraviolet detection system.
