  • Publication number: 20190265357
    Abstract: An electromagnetic wave from a transmitter (100) is emitted toward the outside of a first angular range (AR). A receiver (200) cannot detect an electromagnetic wave reflected at a position somewhat close to a sensor device (10), specifically, an electromagnetic wave reflected at a position apart from the sensor device (10) by less than a distance R1. Specifically, when the electromagnetic wave is reflected at the position apart from the sensor device (10) by less than the distance R1, the electromagnetic wave reaches the sensor device (10) before the first angular range (AR) reaches a Y axis. Consequently, the electromagnetic wave reflected at the position somewhat close to the sensor device (10) is not detected by the receiver (200).
