Abstract
In developing algorithms for remote sensing of chemical and biological warfare agents, it is imperative to have a good understanding of the background radiance signal and environmental characteristics that influence detection. Factors such as thermal contrast, interferent atmospheric constituents, spatial clutter, and temporal variations should all be investigated for both the development and performance modeling of field sensors. To aid in the investigation of these topics as well as to provide data for current simulation tools, JHU/APL has constructed an automated data collection suite capable of simultaneous radiometric measurements in the longwave IR (8μm - 12μm) and midwave IR (3μm - 5μm) while also measuring a host of relevant atmospheric parameters. The primary radiometric sensor, an ABB Bomem MR304, is mounted on a pan/tilt system that is used to scan regions of interest while periodically generating calibration data. This paper describes the system design requirements, specifications of the individual components, and the overall system performance. In addition, data from field exercises are presented.
