Radar Measurements of the Vibration Amplitude
- 4 Downloads
We propose a method for measuring the harmonic vibration amplitude of a reflector using a coherent radar station. A mathematical model describing the dependence of the Doppler spectrum of the reflected radio signal on the ratio of the vibration amplitude to the radiation wavelength is constructed. The vibration amplitude is calculated from the amplitude ratio of the third to first or fourth to second harmonics.
