RADAR APPARATUS AND SIGNAL PROCESSING METHOD THEREIN - A simplified explanation of the abstract
This abstract first appeared for US patent application 18504343 titled 'RADAR APPARATUS AND SIGNAL PROCESSING METHOD THEREIN
Simplified Explanation
Exemplary embodiments of a radar apparatus involve reducing the number of ADCs while maintaining the allowable bandwidth, minimizing chip area and interconnections, and avoiding synchronization issues between ADCs by sampling receive signals from multiple channels simultaneously. This is achieved by setting different frequencies for local oscillation signals used to downconvert receive signals, creating band-limited signals that occupy different positions on the frequency axis. The downconverted signals are then combined and converted into a single digital signal stream for further signal processing in the digital domain to extract target data.

Original Abstract Submitted
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.
