The technique of polarization detection helps improve the ability of detecting and identifying target, which is currently one of the important contents of the research at home and abroad. The measuring principle of infrared hyperspectral polarization was introduced. The measuring system of long wave infrared hyperspectral polarization was set up. The measuring experiments of polarization characteristic of paint-coating and aluminum-plating target at different temperatures and observing angles were carried out. The effective experimental data was obtained and analysed. The results show that: the spectral polarization characteristic of the target is influenced by temperature and observing angle; the more the difference of temperature and observing angle of the target is, the more the spectral degree of polarization is; the spectral degree of polarization has band selectivity. The effective detection and identification is developed based on the difference of temperature and observing angle of targets. The above results provide reference for band selectivity of the detector.
