Fmcw range resolution

WebAs a side note, although the received signal is sampled at 150 MHz so the system can achieve the required range resolution, after the dechirp, you need to sample it only at a rate that corresponds to the maximum beat frequency. ... This example shows how to use FMCW signal to perform range and Doppler estimation in an automotive automatic ... WebOct 12, 2024 · For the range resolution of an FMCW radar, the bandwidth (BW) of the transmitted signal is decisive. However, the technical possibilities of Fast Fourier Transformation used in signal processing are limited in time. The resolution of the FMCW radar is determined by the frequency change that occurs within this time limit.
