Abstract
A radar system and a method for detecting a target using the radar system. The radar system includes a waveform generator, a plurality of phase shifters, at least one mixer, an analog-to-digital converter, a fast Fourier transform (FFT) processor, and a processor. The waveform generator generates a frequency-modulated continuous wave (FMCW) signal including a set of chirps repeated for a predetermined number of times. The phase shifters shift a phase of each chirp on a transmit branch. The phases transmitted via first and second transmit branches are shifted in accordance with first and second sets of regularly spaced phases, respectively. The first and second sets of regularly spaced phases have first and second phase differences, respectively, that are different from each other. The FFT processor performs FFT processing and the processor determines an angle of direction of the target based on range Doppler map bins.
