Paper Abstract

Benefits for the detection of difficult targets have been demonstrated for multispectral and polarimetric imagery in differing conditions. The spectral differences between target and background have been seen to provide an enhancement to target discrimination. However, false alarms can occur mainly due to spectral variations in background materials. Complimentarily, polarimetric imagery has been used to detect man made targets by exploiting the reflective characteristics of man-made objects and the suppression of background clutter; but the detection process can be limited by the geometry and nature of targets. A data gathering SWIR Multispectral-Polarimetric sensor has been built to investigate whether adding polarimetric to multispectral information decreases background induced false alarms whilst maintaining good detection statistics for low contrast targets.
