An adaptive antenna array auto-compensator (automatic transmission) is investigated based on the formation and reversal of the interference correlation matrix (CMP) depending on the change in the interference situation between the setup stage and the working stage of its operation. The ACP based on the projection method and the ACP based on the deterministic compensation method are compared experimentally. During the experiment, pulse and continuous interference were studied.
The article deals with the features of the functioning of an adaptive antenna array's automatic interference compensator (ACP) based on the formation and reversal of the interference correlation matrix (CMP) depending on the change in the interference situation between the tuning stage and the working stage of its operation. The ACP based on the projection method and the ACP based on the deterministic compensation method are compared experimentally.
In the course of the study, it was found that: the quality of interference suppression of AAP ACP significantly depends on the size of the training sample. The number of time samples of the training sample must be at least 2 times greater than the number of antenna elements of the AAR; the presence of even a small part of the useful signal at the stage of setting up the automatic transmission leads to a significant deterioration in the SIG-nal/(interference+noise) ratio. To suppress high-intensity active interference, the formation of wider rejection zones is required; when forming wide rejection zones, the automatic transmission system based on the projection method loses its functionality, and the automatic transmission system based on the deterministic compensation method provides suppression of active interference in wide rejection zones.
