COLLISION AVOIDANCE RADAR BRAKING SYSTEMS INVESTIGATION. PHASE II STUDY. VOLUME I. SUMMARY REPORT

An instrumented test automobile equipped with an automatic/noncooperative radar brake system was used to gather and classify experimental data on radar false alarms as a function of various radar system parameters such as: detection range cut off (RCO), antenna beamwidth, range delay and vehicle velocity. The test vehicle was driven over three roadways under actual traffic conditions within the metropolitan area of Detroit, Michigan. The roadways typify much of the high density, high speed, urban and suburban driving in the United States. Results of the test program showed that both the detection range cut off and antenna beamwidth have a pronounced effect upon the false alarm problem; the range delay and vehicle velocity are of secondary importance. Analytical analyses were also performed to determine the effects of radar design parameters such as beamwidth and frequency on rain clutter and radar detection probability for three target classifications ranging from pedestrians to full size passenger cars. A computer simulation program was employed to evaluate the system cost-effectiveness of 36 system configurations.
