The real and imaginary parts of the signal are used for evaluating the absolute value of the signal sig = sqrt (re^2 + im^2) The sig values is first normalised in the [0-1] range sig_norm = sig/max(sig) and then the values at 1% (m) and 99% (M) are evaluated. The radargram is saturated at low and high values by using m and M, and the contrast is enhanced with the following algorithm sig_enh = (sig_norm - m) ./ (M - m) Finally, the radargram is shifted to adjust for the RANGE_SHIFT value."
