Abstract
A computerized method characterizes a dedicated short-range communications (DSRC) system that includes at least one DSRC device for use with a vehicle-to-vehicle communication system. The method includes positioning a vehicle under test (VUT) with the DSRC system at a first location and positioning a DSRC instrumentation antenna at a second location spaced apart from the first location. The method includes varying an azimuth angle between the DSRC device and the instrumentation antenna by performing a rotation of the VUT in place at the first location or the instrumentation antenna in a circular path about the first location. The method includes, for multiple azimuth angles, testing receive performance of the DSRC system by transmitting DSRC packets through the instrumentation antenna to the DSRC system, estimating an error rate indicating a level of success of DSRC packets being received by the DSRC system, and recording the error rate for each angle.
