A Target Detection Scheme With Decreased Complexity and Enhanced Performance for Range-Doppler FMCW Radar

In conventional fast-ramp-based target detection schemes for the frequency modulated continuous wave (FMCW) radar systems, all chirp sequences are performed fully on two-dimensional fast Fourier transforms (FFTs) to estimate range and velocity of a target, and all range-Doppler cells are scanned by...
