  • Receiver, method of operating the receiver, and beamforming radar system including receiver
    Patent number: 9791561
    Abstract: A receiver, an operating method of the receiver, and a beamforming radar system including the receiver are provided. A beamforming receiver may include a demodulation circuit configured to receive a signal reflected from an object via an antenna, to demodulate the received signal, and to generate a demodulated signal, and a time delay circuit configured to generate a digital signal by processing the demodulated signal based on reference clock signals, wherein the digital signal including static delay information associated with a static motion of the object, and dynamic delay information associated with a dynamic motion of the object.
