Table 2.

Typical values for commercially available radar sensors for distance measurements and ranging taken from representative product manuals (see the citations).

Principle	Frequency	Typical Measurement Range	Precision	Measurement Value Update Rate	Citation
Pulse	25 GHz	0.21 m to 13 m	10 mm ⁽¹⁾	0.5 Hz	[83]
FMCW	24 GHz to 26 GHz	0.2 m to 80 m	$\pm 3$ mm	10 Hz ⁽²⁾	[84]
six-port	24 GHz	0.01 m to 2.0 m ⁽³⁾	$\pm 40$ µm	20 Hz ⁽⁴⁾	[85]

⁽¹⁾ No precision stated in the manual; the given value is the maximum measurement error; ⁽²⁾ No measurement value update rate stated; frequency results from the serial interface; ⁽³⁾ Only evaluated up to 2 m due to distance limitations in laboratory; ⁽⁴⁾ Limited by the utilized serial data interface.
