Multipath angle-of-arrival, amplitude and phase progression measurements on microwave line-of-sight links

In the presented paper the principle of design and work of the equipment for microwave propagation investigations is considered. The equipment lets to carry out multi-channel measurements of fluctuation of amplitude, phase progression and angle-of-arrival of microwaves. The equipment realizes homodyne method of measurements. A new method of angle-of-arrival of microwave measurement is discussed. Several receiving units are not set hard and phase stable feeder is not used. In each of unit there is placed its own oscillator. All of oscillators are not synchronized. Several retransmitting units are not set hard too and let carry out measurements of angle-of-arrival on both parts of testing link.
