Abstract :
Experimental investigations of amplitude and phase progression fluctuations on microwave line-of-sight links are presented. The transmitter unit is represented as a receiver-transmitter device operating for the same antenna. Here the transmitter signal is the heterodyne signal for the receiver. The low frequency channel is used to get in-phase oscillations in both parts of microwave link. The initial phase of low frequency oscillations is transferred on microwave. The microwave propagation and meteorological data are sampled synchronously for all time of experiment. The daily experimental data are presented.
