Advanced wide field of view millimeter-wave radar using orthogonal complementary codes

This paper reports a radar system design using 79GHz millimeter-wave for vehicular and pedestrian safety around intersections. The proposed system design and associated key algorithms are embedded into a prototype and verified in an anechoic chamber and a field experiment. The system covers the distance of 40m and the azimuth angle of 120° range with high range and angular resolution (20cm, 5-degree), and can detect pedestrians within short budget of 100ms by using orthogonal complementary codes which are transmitted by Tx dual beamscanning to suppress the interference between the two divided area. The results therefore prove the system feasibility for future automotive safety application.
