Phase-difference methods for a measurement of small time intervals by use of pseudorandom signals are suggested and its applications for processing of experimental data. The significant influence of tidal oscillations on travel time at Hawaii - Kamchatka path is shown. The possibility of an evaluation of the form of a flexible antenna without use of special basic sources is demonstrated.
