Abstract

Exemplary embodiments provide a radar apparatus having a plurality of antenna elements and enabling to reduce a number of ADCs as long as being allowable according to a bandwidth of the ADC, reduce a chip area occupied by the ADC and interconnections in an integrated circuit, and prevent a synchronization problem between the ADCs by sampling receive signals of multiple channels at once. Frequencies of local oscillation signals used for downconverting receive signals are set to be different from each other by an amount of an offset frequency, so that each of band-limited receive signals obtained through respective RF paths may occupy a different position on a frequency axis of a frequency domain. Downconverted receive signals are combined into a single signal and converted into a single digital signal stream, and a signal processing of the digital signal stream in a digital domain enables to obtain target data.
