Abstract:
On the basis of spectral representation of non-harmonic processes and partial characteristics of antennas dispersion of an assessment of coordinates of sources of regular super-broadband impulses sequences by measurements of time of their arrival by measuring systems is determined. Dependences of accuracy of a fixing of radiators on the directed properties of antennas are investigated. It is shown that dispersion of an assessment of coordinates of radiators of the impulses which period of following considerably exceeds autocorrelation time, decreases in proportion to value of integral from work of partial directed action coefficients transferring and reception antennas in an equivalent strip of a signal on a measuring instrument entrance. The error of a fixing of object decreases in process of increase in the sizes of receptions antenna owing to increase of efficiency of signals interception on lateral petals of the transferring antenna directional patterns.
