Fmcw range resolution
WebAug 6, 2002 · In FMCW radar systems, range resolution depends on the transmitted bandwidth, the processed overlap between the transmitted and received frequency … 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.
