Webuse the Frequency Modulated Continuous Wave (FMCW) radars'3', which have some advantages : 1. The composition of the high frequency circuit in FMCW radar is simpler than that of the pulse radar. 2. The average transmission power in FMCW radar is large and it is advantageous from the viewpoint of signal-to-noise ratio. 3. WebFor FMCW radar applications, due to the fast frequency hops that make up FMCW ramp, the PLL lock time is of high importance. For a PLL paired with single band VCO, the largest factor in lock time is the bandwidth of the loop filter. Higher loop bandwidth gives a fast settle time, but also can increase in-band phase noise.
