Abstract
An FMCW radar transmission and reception apparatus radiates, via a transmission antenna, a beat frequency signal of a frequency modulation continuous wave (FMCW) and then receives, via a reception antenna, a reflected signal obtained from the radiated frequency modulation continuous wave (FMCW) signal that is reflected by a target and returns, wherein the frequency of a beat signal of a frequency modulation continuous wave (FMCW) radar can be effectively adjusted by configuring a plurality of phase locked loops (PLLs) used in a transmitter and a receiver, and using the same reference oscillation signal for the plurality of PLLs.
