In this paper On the basis of spectral representation of non-harmonic processes and characteristics of antennas the error of an as-sessment of the maximum credibility of coordinates of super-broadband of radiators in the difference range finder systems is defined. The analysis of its dependences on the directed properties of antennas of sources of a radio emission and reception posts of system of a fixing, a look and parameters of signals is carried out. Extreme on the electric sizes of aerials and spectral density of capacity of radiation of error of location of objects are found. It is shown that accuracy of measurement of coordinates of a radiator depends not only on its removal, but also angular situation concerning each reception post. The error of a fixing of object decreases with in-crease in value of integral from work of directed action factor of its antenna and spectral density of radiated energy, and also directed action factors of reception aerials of difference range finder system in an equivalent strip of signals on entrances of measuring instruments. Comparison of accuracy of an assessment of coordinates of super-broadband of radiators with indicators, achievable for measuring systems with hypothetical antennas is executed. Possibilities of decrease in error of coordinates of objects at the expense of accumulation of signals in the course of processing are investigated. It is established that accuracy of an assessment of location of a source of sequence of super-broadband impulses raises more slowly, than under the linear law, in view of transformation of their form in the course of transfer and reception.
