WebMay 26, 2024 · I have written a code in MATLAB to determine the range and doppler response of a single target for FMCW Radar. I am able to determine the accurate range of target after performing the first FFT. However, as I determine the 2nd FFT to get the Doppler response, the velocity is accurately determined. However, when I plot the contour map … WebNov 3, 2024 · Various studies on object detection are being conducted, and in this regard, research on frequency-modulated continuous wave (FMCW) RADAR is being actively conducted. FMCW RADAR requires high-distance resolution to accurately detect objects. However, if the distance resolution is high, a high-modulation bandwidth is required, …
