Signal Processing For The NASA Multispectral Linear Array
Abstract
The Multispectral Linear Array Sensor is being developed by NASA as a next generation remote sensor. The development is presently in a competitive design phase. This paper describes the on-board signal processing electronics for the Honeywell design. The signal processing includes focal plane electronics for push broom arrays in six spectral bands, on-board radiometric calibration, digitization, bandwidth compression, and formatting for transmission over a high bandwidth data link. The signal processing must adapt to different detector dwell times and bandwidth compression ratios for three different orbital altitudes. A high degree of fault detection and redundant circuitry is incorporated into the design to meet the high reliability requirements of a space sensor.
