Abstract
The Doppler shift spectrum of coherent radiation scattered from rough vibrating body is studied. The analytical expression for temporal correlation function of scattered field is obtained whereby the different types of scattering surface motion can be analyzed. Estimates of harmonic amplitudes were made the correlation properties of the spectrum were studied. It is found that when vibration amplitude is sufficiently small the set of harmonic amplitudes will fluctuate as a whole and will be highly correlated. With the rise of vibration amplitude the set of odd harmonic amplitudes remains to be highly correlated and so is the set of even harmonics. On further increasing the vibration amplitude the correlation between two sets diminishes and two sets become uncorrelated altogether.
