| With a variety of new optoelectronic technology in military and national production field application, the traditional single mode of search system can not meet the need of the development. Adopt a variety of mode composite photoelectric search system to play the single mode, improve the search performance of the system, meet the needs of practical application. In this field in China develop relatively slowly.In this paper we design a radar/infrared composite search system, have made the related optical path design, infrared detector design, cooling system design, proposed the radar/IR search and the overall scheme design. Infrared/Radar Composite search system uses coaxial structure, infrared detectors and microstrip antenna mounted coaxially, the radar antenna is placed in front of the infrared detector, the radar antenna can be through infrared radiation and at the same time, can block the millimeter wave, all the design could meet the radar and infrared search performance and greatly reduce the mass and volume of the system, effectively improve the search performance. |
