Webwith a prototype of FMCW radar I'm trying to resolve the distance to the target. The Audio card characteristics are as follows: Fs= 44100Hz. So the FMCW radar range resolution is RR=440MHz/c = 0.34m Ts=20ms thus, number of points N=Fs*Ts = 882. I've tried putting the target on various distances 1m, 1.1m, 1.2m, 1.3m all the way to 2m. WebFMCW radar allows the range and velocity of multiple objects to be detected. FMCW radar offers a good compromise between available object data, complexity, and cost. This …
