To develop a lift early warning infrared device
as a part of land or boat (ship) early warning system
the system has the ability to target pre-discovery and instructions invasion. Methods: In support of distant air situation
alerts the enemy aircraft
missiles and other long-range goals
obtain the target type and preliminary judgment of grade
deliver the alarm information to the command system. The infrared alarm device detects the target's own infrared radiation passively
alarms the incoming targets at low altitude and low altitude remote
when radar and other equipment is out of work. Results: The accuracy of entire system reached 20 according the analysis. Conclusions: The device has a full range of complex background
with high sensitivity
high resolution
anti-jamming
fast response time and other characteristics. (2012) Trans Tech Publications

This paper proposes a method for calculating the multi-exposure times fast and accurately when the scene has a high dynamic range
minimizing the pictures needed to take and improving the dynamic range of the CCD system. The proposed method first measures the camera's response function referring [10]. After that the median value of the output picture is adjusted to be in the middle range of the system output by changing the exposure time. It can be inferred from the histogram of the current picture whether it's a high dynamic range scene by calculating the number of pixels under exposed and over exposed. Once again the under and over exposed pixels are adjusted to be in the middle according to the camera's response function. Finally different exposed pictures (2 or 3) are fused together by Gaussian function and the dynamic range is compressed by y correction. Experimental results on UNIQ-UM400 analog camera and a digital acquisition system show that the algorithm works well and solve the problem of low dynamic range of CCD camera. 2010 IEEE.
