Infrared polarization imaging test of typical background in missile range

As a new detection method,infrared polarization has outstanding advantages such as anti-masking and anti-stealth. In the future, it has a large application prospect on new lead and photoelectric pods. Therefore, studying the infrared polarization characteristics of the typical background in missile range is of great significance for target test and evaluation, target and environmental characteristics, missile test, camouflage protection, etc.In this paper, the principle and method of infrared polarization imaging was first studied,infrared polarization imaging tests were carried out for the typical background in missile range,and the change law of Gobi background polarization over time in a day was obtained.Through experiments, the effectiveness of three polarization enhancement methods, such as polarization, polarization difference and pseudo-color, were verified to improve image contrast, providing technical support for the testing of infrared polarization imaging equipment in the future.
