红外反舰导弹成像制导仿真研究

The Image Simulation of the Warship Target and Its Background in the Guiding Head with IR

仿真要素包括舰船和海天背景的红外辐射、大气衰减以及红外成像探测器的噪声影响。对目标背景的红外辐射仿真,可以通过构建几何模型、红外模型和数值模型这三个模型来实现;而大气传输需要考虑的是散射、吸收对红外辐射透过率的衰减;对于红外探测器则是要讨论其电噪声对红外辐射灰度分布的附加效果。

The essential factor of the simulation includes. The IR radiation of the warship target and the sea-sky background, the diminish of the air, and the noise of the detector of IR image. The simulation to the IR radiation of the target and the background can be made by forming three models. The geometry model, the IR model and the data model. To the transmission of the air, the diminish of the penetration ratio of the IR radiation is considered. To the IR detection, the effect of the electric noise to the grey distribution of the IR radiation is discussed.
