ABSTRACT:
A horn antenna part of a radar apparatus is made of a heat emitting material and includes: an antenna body part having a plurality of horn parts arranged in an array form, wherein each horn part is open toward a front surface of the apparatus, and has a diameter which gradually increases toward the front surface; and a feeder part including a waveguide which communicates with the horn parts, wherein the feeder part is connected to the antenna body part. The radar apparatus also includes: a wireless part for generating a high-frequency signal supplied to the feeder part, and converting a reflected high-frequency signal to a medium-frequency signal; and a circuit part for controlling the high-frequency signal and processing the medium-frequency signal. At least one of the wireless part and the circuit part is arranged in a manner such that it contacts the feeder part.
