Experimental investigations of amplitude and phase progression fluctuations on microwave line-of-sight links

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.
