Fmcw ambiguity function
WebThis paper presents a novel sideband sweep nonlinearity software correction method for a frequency modulated continuous wave (FMCW) transceiver based on the high-order ambiguity function (HAF) and time resampling. By emphasizing the polynomial-phase nature of the FMCW signal, it is shown that the HAF processing algorithm is well suited … WebSep 16, 2000 · From the ambiguity function of the linear FMCW signal, the general effects of the frequency sweep nonlinearity on the range performance are discussed. Based on the criteria of determining the Carson bandwidth, an approximate relationship among the range resolution, the target range delay and the mean square root of the nonlinear frequency …
