Abstract:

The Ballistic Modeling Division has made transmittance measurements at selected regions of the electromagnetic spectrum through various aerosols in field environments. The measurements have been obtained with visual, near infrared, far infrared, and millimetre wave instrumentation. Live firings were conducted at Fort Sill, Oklahoma, using mortar- and artillery-delivered hexachloroethane HC and white phosphorous WP munitions. At Fort Hood, Texas, 2.75-inch rockets were launched from helicopters to deliver WP wick-produced smoke. The smoke testing has also included HC and fog oil smoke pots as well as red phosphorous grenades launched from vehicles. The aerosol testing has included measurements through both smoke and dust clouds. A discussion of the tests, the spectral regions measured, the equipment used, the type of data collected, and an analysis of the results are presented.
