Granulometries and pattern spectra for radar signals

Granulometries and pattern spectra are morphological tools used to obtain size distributions in images. This paper presents the application of these techniques to radar signals. It uses a new approach which is more appropriate for RF signals than the classical approach. It uses complex openings, closings and power measurements instead of the usual gray-tone operators and the Lebesgue measure. Examples for simulated and real radar signals are given.
