Characterization of automotive radar targets from 22 to 29 GHz

Automotive radar target characterization from 22 to 29 GHz and 76 to 81 GHz

“…1, is similar to that described previously in [3] with only a few minor differences. In place of the 40 GHz Vector Network Analyzer (VNA), the setup used in this measurement campaign was based on an Anritsu ME7828A VectorStar VNA with measurement capability up to 110 GHz.…”

“…Analogous to measurements presented in [3], we then conducted a series of measurements of the STS sedan, Avalanche pickup truck, Express van, bicycle, motorcycle, and adult standing pedestrian for horizontal polarization. We captured the signal return as a function of distance to target from 0 deg.…”

“…All target return data was calibrated to that of reference trihedral corner reflectors, as described in [3]. The mounting height of the antennas was 57 cm.…”

“…Thus, accurate automotive radar cross section models of various automotive targets are required for high-fidelity autonomous driving system simulators and validation testing [2]. Only a limited set of reports on RCS measurements of targets appropriate for automotive active safety applications have been reported to date [3][4][5][6].…”

“…The main focus of this work was to extend the 22 to 29 GHz automotive radar target characterization presented in [3] to include the 76 to 81 GHz automotive radar frequency band. As such, radar signatures as a function of effective radar bandwidth, polarization, and center frequency have been analyzed and radar cross section (RCS) maps of a sedan, truck, van, pedestrian, motorcycle, and bicycle are presented.…”
