Abstract

It is of interest to achieve rapid scan rates during airborne spectral collection as spatial blur introduced via platform motion can be minimized. Fourier Transform Infrared Spectrometers (FTS) are well suited to this task. Unfortunately, the trade in an FTS between scan rate and resolution approaches an inverse relationship. An FTS simulation has been developed incorporating multiple instrument and scene parameters to evaluate the system-level trade space. Error sources such as uncertainty in mirror velocity during sampling and jitter are included. A detection metric comprised of multiple common detector algorithms is used to characterize system performance. Results are shown characterizing system performance degradation under a variety of environmental and system performance conditions.
