Assessment of methods of decrease in efficiency per copy recognition of means of a radio communication

The reasons of emergence of the individual technical unmasking signs of radio-electronic means are considered. Estimates of dependence of informational content of the individual technical unmasking sign on a total error of measurement at various fixed values of a mean square deviation are carried out. It is shown that for reduction of informational content of a sign possibly application of unification of parameters of transmitters and deliberate change of parameters of a signal.
