【摘要】 基于混浊大气表观调制传递函数的光谱特征，提出一个新的成像质量评价因子作为波段优选的依据，得到了不同波段的成像效果。同时分析了优选波段的影响因素，给出了典型大气条件、典型带宽下的成像优选波段，即在1036～1046 nm、1620～1630 nm波段可得到典型区域相对普适的、良好的成像质量。最后通过成像实验对优选方法的有效性进行了初步验证。更多还原

【Abstract】 According to spectral characteristics of apparent modulation transfer function(MTF) of turbid atmosphere, this paper proposes a new imaging quality evaluation factor to select optimal bands and obtains the imaging quality in different bands. Furthermore, the paper analyzes factors affecting optimal bands and summarizes optimal bands under typical atmospheric conditions and typical bandwidths. It is found that relatively universal and favorable images can be obtained in the bands of 1036-1046 nm and 1620-1630 nm. Finally, the effectiveness of the proposed method is verified by imaging experiments.更多还原
