This work is aimed on development a standard procedure of measurement of different
environmental objects using EPC/GDV method. During investigation several
destabilizing factors influencing the results of EPC/GDV measurements was found.
These factors were analyzed and ways of overcoming them have been formulated.
We have developed a standard recommendations and procedure of conducting
experiments on EPC/GDV that ensures acquiring stable and adequate results. An
algorithm of statistical and mathematical processing of obtained data has been
developed.
Keywords: EPC /EPC/GDV method, standard procedure, natural environment
