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.
Straipsnyje nagrinėjama radaro popaviršutinių signalų skaitinio duomenų apdorojimo morfologines analizės praktinė realizacija, kai skaitiniai duomenys apdorojami kartu su realiais duomenimis. Analizė remiasi skaitinio deferenciavimo algoritmu dažnių srityje. Ji lyginama su centrine baigtiniu skirtumu schema ir demonstruoja vidutiniškai 80 kartu mažesnę skaičiavimo paklaidą.
