摘要：

The possibilities of the method for detecting a noise source, estimating its radial velocity and its distance from the receiver, based on the double Fourier transform of the interference pattern formed during motion, have been considered for a single-receiver configuration. It is shown that, as compared to a signal with a uniform spectrum, the limiting values of the input signal-to-noise ratio, at which the noise source can be localized, increase by about half. The results of a computational experiment are presented. A comparative analysis of the noise immunity of the algorithm applied to signals with uniform and noise spectra is performed.
