PILOT-81 VVA EXPERIMENT-Analysis of the Multi-Path Transmissometer-Radiometer Measurements
Abstract
This report presents results and finding from the PILOTS 1 Emissive Sources Verification Experiments carried out at the Survivability/Lethality Analysis Directorate (SLAD), U.S. Army Research Laboratory Tower site at the White Sands Missile Range during February 1999. The experiments involved (near) simultaneous measurements of direct transmittance and normalized path emission/radiance sampled over three slightly diverging lines of sight through intervening obscurants comprised of either graphite flakes or brass powers of varying concentration levels. Specifically this report presents measurements of direct transmission and total radiance obtained over four spectral bands from the visible through far infrared using the SLAD Multiple Path Transmissometers-Radiometer (MPTR) system augmented with a conventional dual band infrared scanning imager. From the combined transmissometers and radiometer results we are able to determine both the multi-band transmittance and normalized path radiance, or "sky-to-ground" ratio, for cloud optical depths ranging from tau=O to about tau=8.
