The Hann window function for 512 points is plotted in Figure 6. To apply the window function, we multiply the function noting to recalculate it for 256 points to the signal in Figure 1. 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 …
