Abstract:
The automated system for complex measurements of antenna systems is designed for measurment of parameters for largescale antenna (dimensions up to 8x8 m2 and mass up to 5 tons). Installation error of an angles at position of the researched antenna at azimuth and elevation planes doesn`t exceed ±0,05°. Mode control for system functioning in particular, working frequency setting, sweep speed and signal level is established by the operator with the help of computer. For connecting of operator`s place with the transmitting position and the reference channel Wi-Fi is used. Automated system allows it to measure directivity diagrams and frequency characteristics at frequency range 1-26 GHz. For influence reduction of signal reflections from local objects investigated antenna and container with apparatus of the reference channel are located at the hill of 7 m height and the container with transmitting apparatus of mobile position is located at extensible mast of 30 m height.
