Properties of the signal function that takes into account the frequency dispersion in an antenna waveguide path were studied. It was established that the measurement error of distance in a hollow waveguide is greater than the measurement error in free space. An increase is demonstrated in the permissible level of interference at which an estimation of the difference frequency signal relative to the frequency of the global maximum of the signal function is possible.
