ABSTRACT:
A high-sensitivity sensor configuration improves upon airborne hyperspectral and multispectral sensing, particularly for thermal/infrared military target detection and/or identification. The invention combines dispersive spectrometer and filtered TDI detector techniques to provide improved NESR through increased dwell time, along with interband temporal simultaneity and spatial registration. Embodiments relating to hyperspectral, multispectral, and dual-band arrangements are disclosed.
