PURPOSE: A radar transceiving system is provided to improve a signal process speed by processing a received signal in parallel. CONSTITUTION: A plurality of antenna groups(201a,201b,201c) receives a received signal reflected by an object. A plurality of combining units(202a,202b,203c) combines the received signal through the plurality of antennas. A plurality of low noise amplifiers(203a,203b,203c) amplifies the received signal outputted from the plurality of combiners. A switch(204) selects and outputs one of signals outputted from the plurality of low noise amplifiers. A double coupler(100) extracts a transmission signal and outputs the extracted signal as a local oscillating signal.
