Analytical multifrequency phase method of distances measuring

Introduction. Existing methods for measuring broadband over distances do not allow further raise the accuracy and distinguishing ability, because it leads to further unnecessary complication equipment. Phase methods have the distinguished ability. Developed multifrequency phase methods can both raise the accuracy and distinctive ability and significantly narrow the frequency range of measurement signals. Requirements for document. The many analytical frequency methods of measuring objects distances are examined in this paper. It is shown that the proposed approach can be extended to any number of objects by measuring the phase shift and amplitude harmonic signals in a given frequency range with uniform reflected from step three and four objects and solving the corresponding system of equations. It is necessary to use two times more frequency than objects measuring the distance to objects. Conclusions. This approach allows us to develop methods for Multiphase ranging many objects. Further improvement approach should be performed in feasibility study to use in radar, and also to measure the radial velocity measuring the Doppler frequency shift.
