DEVICE AND METHOD FOR PROCESSING RADAR SIGNAL, AND RADAR SYSTEM INCLUDING THE SAME

A device for processing a radar signal may include a pre-acquisition unit configured to, during a first period within one scan period, perform two fast Fourier transforms (FFTs) on a first signal, perform digital beamforming or non-coherent integration and peak extraction, and determine a bin-reject...

Beschreibung
Zusammenfassung:	A device for processing a radar signal may include a pre-acquisition unit configured to, during a first period within one scan period, perform two fast Fourier transforms (FFTs) on a first signal, perform digital beamforming or non-coherent integration and peak extraction, and determine a bin-rejection mask based on extracted peaks, and a normal-acquisition unit configured to, during a second period longer than the first period after the first period within the scan period, perform two FFTs on a second signal different from the first signal, perform digital beamforming or non-coherent integration and peak extraction, determine a Doppler component of a target, determine a virtual channel vector, and acquire information on the target based on the virtual channel vector.
