反舰导弹红外成像制导工作波段的选择是一项重要而又复杂的工作。首先对海面舰船目标的红外特性进行理论分析; 然后选择中纬度夏、冬两个季节, 白天海洋消光系数、自置气象视距气溶胶模式作为两个典型的大气模型, 并利用光学大气传输计算软件 ART2100计算典型大气模型条件下的红外传输透过率; 最后结合理论分析和计算结果, 对中波和长波红外制导优劣进行分析研究, 得出工作波段选择的参考依据。

The selection of working band of the anti-ship missiles seeker which is guided by infrared imaging is an important and complicated task. Firstly, this article analyzes the theoretical infrared characteristic of the sea-surface ship targets, and then chooses the mid-latitude in summer and winter two seasons, marine extinction coefficient in the daytime, and sets up the aerosol model respectively as two typical atmospheric models, and computes the infrared transmission of typical atmospheric model through optical software ART2100. Finally, combining with theoretical analysis and calculation results, we get the reference frame of selection of the working band by analyzing the advantage of infrared guidance based on medium wave and long-wave.
