Abstract

In recent years there has been an increased interest in using polarimetric imaging sensors for terrestrial remote sensing applications because of their ability to discriminate manmade objects in a natural clutter background. However, adverse weather limits the performance of these sensors. Long Wave Infrared (LWIR) polarimetric sensor data of a scene containing manmade objects in a natural clutter background is compared with simultaneously collected environmental data. In this paper, a metric is constructed from the Stokes parameter S1 and is correlated with some environmental channels. There are differences in the correlation outputs, with the sensor data metric positively correlated with some environmental channels, negatively correlated with some channels and uncorrelated with other channels. Results from real data measurements are presented and interpreted. An uncooled LWIR sensor using an achromatic retarder to capture the polarimetric states performed the data collection. The environmental channels include various meteorological channels, radiation loading and soil properties.
