Abstract: | A method of quasi-optimal processing of laser Doppler vibrometer (LDV) signals in the case of monoharmonic vibrations is considered. Under certain assumptions, the problem of quasi-optimal estimation of the information parameter of the LDV signal, related through a known constant multiplier to the relative amplitude of vibrations, is solved. A structure of the device for optimal estimation is proposed. Conditions of optimality of the method are given. Statistical characteristics of estimates of the relative vibration amplitude are investigated by a numerical modeling method. The error of these estimates is compared with the Rao-Kramer bounds. |
