Deriving the Resolution Equation of an FMCW RADAR

WebFMCW radar allows the range and velocity of multiple objects to be detected. FMCW radar offers a good compromise between available object data, complexity, and cost. This … 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). In a pulsed Doppler radar ... WebThe Audio card characteristics are as follows: Fs= 44100Hz.

WebThis paper presents a low-power multi-modulus programmable frequency divider for a frequency synthesizer operating in the 19.25-20.25 GHz frequency band from a reference frequency of 40 MHz. The divider consumes 14 mW of power and is capable of producing divide ratios in the range of 481.25-506.25 with a fine resolution of 1 MHz. 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.
