Radar apparatus having arrayed horn antenna parts communicated with waveguide
First Claim
1. A radar apparatus comprising:
- a horn antenna part for emitting radio waves to space and receiving reflected waves with respect to the emitted radio waves from space, wherein the horn antenna part 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;
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,wherein at least one of the wireless part and the circuit part is arranged in a manner such that it contacts the feeder part.
