选择合适的工作波段对获得性能优越的红外探测系统具有十分重要的意义。通过对红外探测 系统与高光谱遥感工作波段的选择原则进行比较，从探测原理出发，结合高光谱遥感类间可分性的波段选择思想，发展 了一种基于作用距离的波段选择方法。仿真结果表明，这种方法是可行的，能有效地计算出符合要求的工作波 段参数。

It is very important for a high performance infrared detection system to select an appropriate operating waveband. By comparing the operating waveband selection criteria of infrared detection systems with those of hyperspectral remote sensors, a waveband selection method based on working distance is proposed according to the detection principle and the hyperspectral classification. The simulation result shows that this method is feasible and can be used to calculate the desired operating waveband parameters effectively.
