3 FMCW

FMCW provides the simplest modulation scheme to achieve wide range and high accuracy when measuring distance. FMCW also provides the mean for speed measurement in the radial dimension (the line between the radar and the target) – either a high speed, like that of a car, or a lower speed, like how a chest rises and falls while breathing. The tracking of such small movements is often referred to as Doppler or micro-Doppler detection.
