With FMCW you can get distance. When you sweep the output frequency upward the round-trip time causes the received signal to be at a lower ('older') frequency than the current outgoing signal. The frequency difference is measured the same as a doppler-induced frequency difference. Knowing how rapidly the output frequency is changing allow you to measure the round-trip time and thus the distance.
If you alternate between sweeping up in frequency and sweeping down (triangle wave modulation) any speed induced doppler shift will always shift the frequency down when receding and up when approaching. This causes one distance measurement to be low and one to be high. The difference in distance measurement sweeping up and down should let you calculate the speed and averaging the two distances should get you close to the true distance.
