Performance
Scientific paper
Data collection for Earth resources applications requires sensors with high sensitivity, moderately high scan rates, large dynamic range, and excellent calibratability and stability. In addition, multispectral or hyperspectral capabilities are highly desirable to enhance scene discrimination, chemical species identification, and temperature measurement performance. These sensors must also have small size, light weight, low power, reduced thermal load, and simple electronic interface characteristics for improved mission performance. A collection of focal plane technologies is currently being developed to meet these requirements: (1) High-speed (18 kHz) 224-channel scanning InSb sensor chip assembly with 52 in TDI. (2) On-SCA 450- channel, 24-kHz, 12-bit A/D converter. (3) 208-color SWIR- MWIR hyperspectral and 3-color SWIR-MWIR multispectral solid-state spectrometers. (4) Cryogenic digital optic data links. Prototype components have been fabricated. Initial performance measurements have successfully demonstrated the feasibility of these emerging focal plane technologies.
