Paper Abstract
A CO2-ladar system is used for measurements. The signal from the system is a sinusoidal FM-modulated multi-component signal. To extract the modulating frequencies time-frequency representations, e.g., the Wigner-Ville distribution and the Choi-Williams distribution are used. The estimation method is applied both to simulated and real data. Estimation of the vibration frequencies is shown to be feasible even for low SNR, e.g., -4 db.
