| 摘要 |
The present invention relates to a wideband frequency detector and, more particularly, to a frequency detector for detecting a radar signal for inducing the safe driving of a vehicle by determining all signals and the velocity of the vehicle. To this end, the wideband frequency detector of the present invention includes: a horn antenna receiving a signal having a specific frequency; a first amplifier receiving the signal having the specific frequency from the horn antenna; a mixer receiving a signal low-noise-amplified in the first amplifier from the first amplifier; and a second amplifier disposed in parallel with the first amplifier and amplifying the signal received from the horn antenna in order to deliver the amplified signal to the mixer. |
