Abstract: Active imaging systems can provide increased contrast-to-noise ratio (CNR) and targeting performance over passive systems in low-light and long-range applications. We use both a radiometric model and the Night Vision Integrated Performance Model to compare the performance of active continuous-wave (CW) and laser range-gated (LRG) imaging systems with laser illumination at 1.6 and 2.1 μm, corresponding to the shortwave infrared (SWIR) and extended SWIR (eSWIR) bands, respectively. The imager performance is characterized by CNR as a function of range, as well as pixels-on-target. The modeling results demonstrate increased performance in the eSWIR band over the SWIR band in the majority of cases and increased performance for LRG systems over CW systems in all cases. The in-progress design of an active imaging testbed to confirm these modeling results with field imagery is discussed. [ABSTRACT FROM AUTHOR]
