Design and Analysis Approach for a Rapid Response Hyperspectral Imaging Mission

摘要

The Air Force has expressed interest in a tactically effective hyperspectral imaging payload for use in a rapid response demonstration program. The goals set for a high quality imaging spectrometer payload includes radiometric performance (sensitivity, saturation range, quantization level, and absolute radiometry accuracy), spectral performance (spectral range, resolution, sampling, and spectral calibration accuracy), spatial performance (image swath width, image length, spatial resolution, ground sample distance, and geolocation accuracy) as well as mission constraints related to payload weight, volume, power, and data rate. Raytheon has developed a number of design tools needed to balance these requirements using real-world hyperspectral detection case studies that relate directly to military tactical effectiveness. These techniques make use of high quality imaging spectrometer data sets from airborne collects to enable evaluation of probability of detection versus probability of false alarm for arbitrary spectral target sets. In this way, reasonable surrogate metrics for tactical military utility may be examined as a function of payload performance requirements in order to perform meaningful cost-as-an- independent-variable (CAIV) analysis.
