Abstract

The article considers the issue of creating the adaptive matrix receivers with the automatic control system installed on the adaptive platform such as SEMS (Smart Electromechanical System). It analyses the dynamics of mirror systems within large diameter antennas in the movement. Engineering formulas to calculate the optimal pixel sizes of adaptive matrix receivers are obtained as a result. These matrix receivers can be used within the radio telescope control system to adjust the high operation speed at a defined sensitivity. In some cases, the installa-tion of the matrix receiver on the SEMS platform can reduce significantly the effect of fluctuations in the focus of the antenna due to wind and weight disturb-ances by measuring these oscillations and compensating for them by appropriately shifting the platform with the matrix receiver.
