Abstract

This paper has carried out experiments on the influence of spectral resolution and channel number on the camouflage target recognition of imaging spectrometer. Based on the measured data, the camouflage helmet is selected as the spectral curve of camouflage target for resampling, and the spectral curve obtained under different spectral resolution and channel number conditions is simulated. Qualitative analysis is carried out by graphic method, interpolation operation is carried out on the resampling spectral data, and quantitative analysis is carried out by using SAM (Sepctral Angle Mapper) method. The resampling target characteristic spectral curve is compared with the original spectral curve in different ranges. The experimental conclusion is obtained by analyzing the spectral characteristics of the camouflage target under different spectral resolution and different channel number conditions, it can provide theoretical basis and technical support for the determination and optimization of spectral resolution and channel number of imaging spectrometer used for camouflage target recognition.
