The practical realization of the morphologic analysis of radar subsurface as the processing of input digital data is presented here together with real data processing results. The analysis depends on a new numerical differentiation algorithm in frequency domain. It is compared with a central finite differences scheme and results of computations demonstrate approximately 80‐times decrease of the maximum errors.
