摘要： A method for object detection within an elevator car including: transmitting radar signals at a selected polarization into an elevator car towards an individual; receiving reflected radar signals at a reflected polarization; comparing the reflected polarization to the selected polarization; determining that the individual is in possession of a metal object in response to comparing the reflected polarization to the selected polarization; and activating an alert in response to the determining that the individual is in possession of the metal object.
