Measurement of Parasite Doppler Effect in Radar Systems using Laser Heterodyning Techniques

摘要

The paper deals with development and realisation of a heterodyne He-Ne laser Doppler system able to measure from distance the mechanical vibrations of a radar antenna. These vibrations, caused by wind and/or by proper system, could give false information concerning the velocity of a target. To measure the frequency and the amplitude of mechanical vibrations we used the optical heterodyning technique.
