Abstract. Self-organizing broadband signal antenna system is
suggested for radio relay, troposcatter and satellite communication systems in
conditions of dynamic signal noise. The system is operated on the principle
peak-holding (optimizing) control using orthogonal search oscillations and
synchronous detection. In the search and synchronization mode adjustment is
carried out not under the maximal signal/interference +noise as in commonly
used systems, but under the minimum of total signal strength and noise. After
the ratio of signal/interference +noise at the output reaches threshold value
the system is managed under the broadband signal convolution. The system is
compatible with mirror, hybrid mirror, bird cage (cylindrical) antennas and
hemispherically scanned antenna arrays with isotropic direction characteristic.
Keywords: broadband signal, interference,
convolution, peak-holding (optimizing) control, antenna.
