The IVS-362 radar module was firstly calibrated by pointing it up into the air and then a 500mm x 500mm metal sheet was positioned about 3m directly in front of it. The FT graph above clearly shows a set of readings indicating distance. We expected the set of spikes on the graph to move to the right slightly as the metal sheet was moved away, but the maximum range seems to be 3 m.

The abbreviation FMCW stands for Frequency-modulated continuous-wave radar.
