Abstract:Through the analysis of the survival probability of a tank, the fact that it is difficult for a tank to counter the infrared imaging guided anti-tank missile only by means of zigzag motion and reinforced armor is clarified. A new camouflage method which combines infrared coating materials with interference is proposed. The calculation results for the AGM-64D missile have shown that the survival probability of a tank can be increased greatly by using this method.

Abstract:When an IR CCD (Infrared Charge Coupled Device) is directly illuminated by the sun or works for a long time, the thermal halo background in the infrared image sequences can be observed. The luminance and contrast of the image obtained by the IR CCD are generally low, so the influence of the thermal halo background on the IR image is serious. In order to eliminate the influence of the thermal halo, a method of real-time IR image background compensation by using the digital image processing means - subtraction, reversed addition is submitted. Then, a hardware designed on the basis of those methods is used to implement in the FPGA (field programmable gate array) in real time. The experimental result has indicated that the image's quality can be improved by the thermal halo background compensation.

Abstract:This paper investigates into the latest research and application of space doublesided scan mirrors. The investigation has indicated that double-sided scan mirrors have obvious advantages over other imaging mirrors and have great potential in space applications
