Abstract:
The present invention uses a simple configuration to prevent radar losses resulting from a windshield, in a vehicle, that uses laminated glass. An emission unit of an antenna is disposed inside a vehicle windshield formed of a plurality of layers. The emission unit radiates electric waves and receives reflected waves, from among the radiated electric waves, reflected by an object. A ranging information generation unit is connected to the emission unit. The ranging information generation unit measures the distance to the object and generates ranging information on the basis of the radiated electric waves and the reflected waves from the object.
