Abstract
The Littoral Airborne Sensor, Hyperspectral (LASH) system is a stabilized, hyperspectral pushbroom sensor capable of high-resolution imaging. We have implemented a sub-pixel detection algorithm based on stochastic mixing models and integrated this with the LASH hardware/software system for real-time operation and detection. Initial field tests have demonstrated reliable detection of high contrast targets down to the 30% sub-pixel level with false alarm rates less than ~ 10-7. The LASH sensor system thus provides a powerful tool for detecting small targets over large search areas, making it a valuable tool for search and rescue and a wide range of other applications.
