Methodical approaches enabling full and correct analysis of results registered above typical forest territory in midland of the European part of Russia by simultaneous observations of L-band SAR PALSAR and visible/IR radiometer AVNIR-2 from board of Japanese satellite of ALOS-2 are presented. Main purpose of work is to retrieve and to precise complex dependences of specific radar cross section (SRCS) on HH and HV polarization and spectral brightness (SB) in visible and Near Infrared bands from species, age and an average standing forest stock during summer and winter seasons. To this end the forest census data are engaged in work along with EO data for observed forest plots. Essential attention was paid to ensuring physical homogeneity of basic objects of analysis – forest plots. The developed techniques were applied to EO data for sites of experimental forestry “Russian wood”. Received results give evidence on the essential potential of SAR for EO of forest state retrieval in conditions typical for midland of the European part of Russia. In addition applicability of developed algorithms for mapping of indicative characteristics of Russian woods is confirmed.
