Abstract

An experimental program was conducted to investigate the reflectivity of moving motor vehicles using a Ka-band CW Doppler radar, as well as the accuracy of speed measurements as a function of parameters such as antenna polarization, beam illumination, side distance, multipath, antenna height, signal-to-interference ratio, and aspect angle. The experimental setup used a stationary dual-channel 35-GHz CW Doppler radar with selectable transmit polarization, direction-of-motion-sensing capability, and a signal recording system. The results of the experiments provide basic data for the design of law-enforcement radars at Ka-band. The dominant scatterers and their location on the vehicle were determined.<>
