Research On Search System Technology Of Long Line Array Infrared Imaging

InfraredSearch and Tracking system is one of the key equipment of modern optoelectronic countermeasure technology.It is mainly aimed at the high performance aircraft and precision guided missile which is based on low altitude and low altitude.When the radar is blind,it can support or replace the work.Because of its passive and anti stealth capability,it is considered as an important replacement system for radar.Long line array infrared imaging search technology is the technology of high performance infrared search and tracking system.It has the characteristics of large field of view and high resolution.It can meet the needs of search reconnaissance and battlefield surveillance.Therefore,it has the advantages of low efficiency,low efficiency and high false alarm rate.This research is mainly based on the ground of the“air defense warning device”,which is developed by the European Thales Co,and is based on the ADAD system,which is based on the 1152X4 focal plane array detector.Focusing on the completion of the optical system of periscope,two-dimensional search stable servo control,signal processing,comprehensive display four key technologies in the design and analysis of control,and finally completed the prototype,through the experiment has proved that this design can satisfy the requirement of use.
