<p><P>PROBLEM TO BE SOLVED: To provide an inspection device capable of verifying on the operation performance such as a detailed radio reflection characteristic of a transmission object of a radio wave, and verifying easily the detailed installation state (the place, the depth, the inclination or the like on a road) of a buried radio transmission object. <P>SOLUTION: This device is equipped with a transmission antenna of the radio wave, a reception antenna for receiving a reflected wave from the radio transmission object, and a display part for displaying the state of the radio wave received by the reception antenna. The device is also equipped with the transmission antenna of the radio wave, a reception antenna for receiving a reflected wave from a lane marker performing multiplying reflection of the radio wave from the transmission antenna, and an intensity determination part for determining whether the intensity of the radio wave received by the reception antenna is in a prescribed range or not. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
