Example of a time-profile extraction and fit on SHARAD product 2545801 using the EMI-free frequency band of 15.5056 MHz. The dashed vertical black lines on the dynamic spectrum represent the portion of the product that was fed into the fitting subroutine. The coefficients displayed next to the fitted curve correspond directly to those of Eq. (11). The rise and decay time t_r and t_d were derived as the first and second HWHM. The maximum was computed as the difference between the maximum of the curve and the floor parameter b.
