Abstract: Dedicated short-range communication (DSRC) systems, designed to enhance the efficiency of highway travel, have been proposed for operation in the 5850– to 5925-MHz band. The successful operation of these communication systems depends upon their compatibility with high-power search and tracking radars that operate at or near this frequency band and are a potential source of interference. This report presents the methods and results of a series of interference tests performed by the Institute for Telecommunication Sciences to determine the electromagnetic compatibility of a DSRC system and high-power 5-GHz radars.

Keywords: electromagnetic compatibility (EMC); interference; high-power radars; dedicated short-range communications (DSRC) systems
