The error of measurement of distance for range finders with weight averaging difference the frequencies, caused by parasitic frequency modulation because of influence on the generator an echo of the signals reflected from useful and stirring objects is considered. The parities are resulted, allowing to analyze error size at processing signal difference frequency with parasitic frequency modulated. Requirements to performance antenno - feeding devices and to parametres of weight function are defined.
