Development of millimeter-wave radar for latest vehicle systems

Abstract

We developed the millimeter-wave radar that adopted both the FM-pulse Doppler method and the Polarization-twisting Cassegrain antenna with mechanical scanning. Our radar features the following advantage: • Wide target distance detection range with high distance accu-ray • No "ghost" output for multiple target detection • Superior accuracy of lateral position and excellent separation performance of vehicles running side by side Those advantages are proven with the prototype millimeter-wave radar we developed.
