Attenuation and Multipath Effects on Ground Vehicle Signatures for 94 GHz Sensors
Abstract
The Joint United States-Canadian Obscuration Analysis for Smokes in Snow, also know as Smoke Week XI, was conducted from February 20, 1989, through March 10, 1989, at the Defense Research Establishment in Valcartier, Canada. The purpose of the exercise was to evaluate the performance of variety of sensors under simulated hostile battlefield environments. These environments include extreme cold, falling snow, and a variety of smoke obscurants over snow-covered terrain. Military vehicles including a Leopard Tank and Armored Personnel Carriers (APCs) were used as targets, as well as a number of corner reflector and dihedral test targets on a fully instrumented test site. This report presents detailed results of the analysis performed on the data collected during Smoke Week XI by the Rockwell Instruments Millimeterwave System (RIMS) operating at 94 GHz. Measurements of snow attenuation, smoke attenuation, snow backscatter, and multipath reflection coefficient were taken at near zero degree grazing angle. The effects of smoke and snow on high range resolution profiles of a Leopard Tank and an M113 APC are also presented. Results are compared to other published results where available.
