Methods of statistical diffraction theory have been used to investigate the parameters of interference noise which arises in a tropospheric channel due to interfering reflections from an underlying surface. It has been assumed that the explicit form of the bistatic scattering cross section of radio waves by a randomly rough surface is known. The systematic errors in measuring the signal parameters, the energy spectra, and the variances of the fluctuations in the values of the parameters relative to their average values have been determined. The spectrum of the fluctuations in the bearing of a point source moving horizontally above a rough surface having mildly sloping roughnesses has been calculated.References
