Title
Estimation Of Coupling Between Mobile Vehicular Radars And Satellite Radiometers
Abstract
Coupling of emissions from wideband vehicular collision avoidance radars into passive microwave satellites can impart significant interference to earth remote sensing applications. One of the most physically obvious coupling mechanisms is reflection of the main lobe of the radar by another vehicle toward the main lobe of the radiometer. Since vehicular radars will commonly illuminate another close-in leading vehicle it is suspected that such scattering scenarios will be commonplace. In order to estimate the interference from a collection of such vehicular radars to a passive microwave satellite we performed numerical simulations to determine the system coupling coefficient C-sm,. The only reflection taken into account is that from the rear window of the leading vehicle. We considered three typical styles of automobiles having rear window angles of 25degrees, 35degrees, and 45degrees. It is shown that reflection of radiation from vehicular radars from the rear windows of automobiles can alone easily cause a significant amount of coupling (-10 to -20 dB) with space-borne radiometers. Additional scattering can be expected from other metallic parts of the leading automobile and by other nearby objects such as trees, railings, barriers, and the tilted roofs of buildings.
