1. A radar apparatus supporting long range and short range radar operations, comprising:
- a signal processing unit configured to generate control signals for generating chirp signals used for a transceiving mode selected from the group consisting of a Short Range Radar (SRR) mode and a Long Range Radar (LRR) mode;
a transmitter configured to generate the chirp signals used for the transceiving mode based on the control signals received from the signal processing unit and a predetermined modulation scheme; and
a plurality of transmitting array antennas configured to transmit the generated chirp signals,wherein the transmitter comprises a plurality of power amplifiers being connected to the plurality of transmitting array antennas, respectively, and configured to differently amplify transmission power of the chirp signals according to the transceiving mode.
