Abstract : The article examines the statistical properties of beat signals in radar systems with inner coherence under conditions where the signal is reflected from extended rough surface. The power spectrum, autocorrelation function, and other statistical characteristics have been found by the phenomena-logical-modeling method. The general solution is valid for a broad class of emitted continuous-type signals and is exemplified by an illustration of the Doppler velocity meter with monochromatic radiation and of a radio altimeter with frequency modulation.
