Abstract
This paper describes adaptive signal processing techniques that utilize spectral and temporal information provided by passive infrared imaging sensors to enhance the detectability of sub- pixel targets in clutter. The approaches are directly applicable to advanced sensors like the DARPA-sponsored MUSIC instrument, which are capable of collecting multi-spectral frame sequences in the thermal infrared region. The performance of several algorithm concepts is demonstrated by processing dual-band frame sequence data taken by the MUSIC sensor. The examples also demonstrate the importance of accurate frame registration prior to multiple- image signal processing.
