Worldwide Assessments of Laser Radar Tactical Scenario Performance Variability for Diverse Low Altitude Atmospheric Conditions at 1.0642 μm and 1.557 μm

Spatial, spectral and temporal variations in operating conditions are major contributors to the expected variability/uncertainty in system performance. The ratio of signal-to-noise ratio (SNR) based on climatological data to a standard atmosphere is the primary performance metric used, with results presented in the form of histograms and maps of worldwide LADAR performance variation. This metric is assessed at 2 wavelengths, 1.0642 μm and 1.557 μm, for a number of widely dispersed land and maritime locations worldwide over oblique and vertical air to surface paths in which anticipated clear air aerosols and location specific heavy rain and 150 m thick fog occur.Abstract excerpt © SPI
