Abstract
Space-based remote sensing instruments used in Earth resource monitoring applications need to provide multispectral (PAN, VNIR, SWIR), wide field of view (WFOV), small ground sample distance (GSD), and high SNR performance. Focal Plane System's used in these applications must provide high sensitivity, small pixel size, and large numbers of cross-scan pixels, in small, light weight, low power hardware configurations that provide simple electrical interfaces. In 1997, Raytheon delivered a MS/PAN FPS as part of NASAs Earth Observing-1 program. This program provided flight validation data for key FPS technologies that are the foundation for today's multispectral, focal plane systems. Since 1997, there have been a multitude of technology advancements which significantly enhance the performance capabilities of today's FPS designs: Hybrid SiPIN and SWIR HgCdTe detector array/CTIA ROIC pixel area reduction; Improved CTIA transimpedance gain, read noise, linearity, electrical power and uniformity performance and Focal Plane Electronics size, weight and power performance improvements.
