Abstarct. Common adaptive circuits
use priory information on difference in the direction of the desired signal and
suppressed interferences arrival, which results in the inability to provide a
required ratio of the desired signal strength to the interferences strength in
the conditions of priory ambiguity of time-varying directions of the desired
signal and interferences arrival. In the suggested algorithm it is managed under the two-loop
circuit for the interference and the high-precision broadband signal under the
principle of 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.
