Deriving the Resolution Equation of an FMCW RADAR

Webmeasurement resolution is not dependent on the formula ΔL=c/2n·B, where B is the scanning range of the tunable laser[4, 18, 20], which is suitable for all FMCW laser distance measurement systems mentioned above. So for this FMCW laser distance measurement system, the requirements for laser scanning range can be reduced. WebThere are two main advantages of FMCW radars: the low peak power needed for the CW signal (less overall power consumption) and the independent choice of velocity and range resolution, the latter being defined by bandwidth rather than the sweep duration (or pulse repetition period) as in pulsed systems (see Table 6).
