Abstract
Radar loss caused by a windshield having laminated glass in a vehicle is suppressed with a simple configuration. An antenna's radiation section is disposed inside the windshield of a vehicle having a plurality of layers. The radiation section not only radiates radio waves but also receives reflected waves of the radio waves from a target. A distance measurement information generation section is connected to the radiation section. The distance measurement information generation section measures a distance to the target on the basis of the radiated radio waves and the reflected waves from the target and generates distance measurement information.

A distance measurement apparatus comprising:
- a radiation section disposed inside a vehicle's windshield and adapted to radiate radio waves and receive reflected waves of the radio waves from a target;
- and
- a distance measurement information generation section connected to the radiation section and adapted to measure a distance to the target on a basis of the radio waves and the reflected waves and generate distance measurement information, wherein
- the windshield includes laminated glass including a first glass layer, a second glass layer, and a resin layer sandwiched between the first and second glass layers, and
- the radiation section is disposed between the first glass layer and the resin layer.
