Abstract:

The objective of the Navy Background Measurements and Analysis Program BMAP is to satisfy the data requirements for design of surface, and air-based infrared IR search and track devices. The IR backgrounds data are acquired with a sensor that has high spatial resolution, high sensitivity, and simultaneous 4 to 5 micron8 to 11 micron capability. Laboratory test show that the 8 to 11 micron detector array has an undesired ground resistance that introduces weak electrical resistive coupling among the detector channels, giving rise to spatial defects in the long-wave data. Techniques are developed for inverting the focal plane resistive network, effectively decoupling the detector channels and eliminating the spatial artifacts, without smoothing the data or degrading noise performance. Originator-supplied keywords include Data correction.
