Abstract

The paper reviews the relevant development status of domestic and international solar blind ultraviolet and infrared warning, According to current application demands for the payload of the missiles warning in the near-space, this paper presents a dual-band early warning system, which covers the solar blind ultraviolet (250nm-280nm) and MWIR (3000-5000nm). The system uses dual-band to achieve military missile detection and warning, which can effectively reduce the false alarm rate. The optical system uses a four off-axis system as the main anti-optical systems and the splitter was introduced to realize on two spectral bands. According to the detector and the corresponding application needs two-band optical system, this paper completed the calculations and optical system design. After the design is complete, MTF two bands of the optical system in the Nyquist frequency are: solar blind ultraviolet MTF>0.8@39lp/mm, MWIR MTF>0.7@39lp/mm, The maximum RMS spot diameter of two optical systems are smaller than the size of a detector, The single energy cell concentration is greater than 80%.
