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. ina mordhorst achimWebThe FMCW radar overcomes this problem and can support very close-range targets.
