Abstract

Lidar measurements using ruby (0.7-μm) and CO2 (10.6-μm) lidar systems during the dustry IR Test-1 are described. The test was conducted at the White Sands Missile Range (WSMR) in October 1978. Transmission comparisons are made between the two wavelengths through dust and smoke clouds generated by artillery barrages, TNT explosions, and oil–rubber fire in a test zone midway (1 km) along the lidar path. A target at the end of the lidar path provided a reference backscatter return for the transmission measurements. Results indicate that the broad particle size distribution present in the dust generated at WSMR produced little if any wavelength-dependent transmission effects.
