Measurements of Millimeter Wave Radar Transmission and Backscatter during Dusty Infrared Test II (DIRT II)

摘要

Recently there has been much interest expressed to determine the ability of millimeter wave radar to perform target acquisition during degraded visibility conditions. In this regard, one of the primary issues of concern has been the potential of high-explosive artillery barrages to obscure the battlefield from millimeter wave radar systems. To address this issue 95-GHz millimeter wave radar measurements were conducted during the Dusty Infrared Test II (DIRT II). This test was held at White Sands Missile Range, NM 18-28 July 1979. Millimeter wave transmission and backscatter measurements were performed during singular live firings and static detonations of 155-mm and 105-mm high-explosive artillery rounds in addition to static detonations of C-4 explosives. A brief description of the millimeter wave portion of the test and instrumentation is given. The data along with some preliminary conclusions are presented.
