Field tests of a 76GHz automotive radar with the dielectric lens and SAGE algorithm

Abstract

Novel automotive radar of 76 GHz band has been manufactured and the field tests have been successfully carried out. The radar features by applying SAGE algorithm to the multi-beam dielectric lens. For simple structure and small size, we used a patch array antenna as feed. Under severe constraints of the size, the lens shape has been designed by multi-objective genetic algorithm. Through the field test, it is confirmed that 2 targets separated by 3.5m can be resolved over the range from 20m to 80m.
