Abstract

The paper discusses the issues of studying the autocorrelation functions of radio signals reflected from rotating fan blades. A brief overview is given of the techniques conventionally used to isolate signals caused by propeller modulation, and a general analytical formula is obtained for the autocorrelation function of a signal with a quasi-periodic spectral density. The results of modeling of signals reflected from a rotating fan are presented.
