radar sensor

Abstract

The purpose of this invention is to provide a radar sensor capable of accurately determining the degree of deformation or shape deviation of an object. The radar sensor of this invention comprises: a transmitting antenna capable of transmitting radio waves toward an object; a receiving antenna capable of receiving radio waves reflected by the object; a first reflector capable of reflecting the radio waves reflected by the object back to the object; and a detection unit that detects the distance to the object based on multiple reflected waves (i.e., radio waves transmitted from the transmitting antenna, reflected by the object, reflected at least once by the first reflector, and received by the receiving antenna).
