In many engineering applications, in order to improve the aperture utilization rate of the antenna, the array surface arrangement of the common-aperture dual-band composite phased array antenna is adopted, the real-time requirement on the beam control device is high, the size of the beam control device is strictly limited, the traditional single-band beam control device is different from the traditional single-band beam control device, and the design of the beam control device is difficult only by controlling the phased array antenna with one band.
How to realize the simultaneous control of the dual-band antenna, reduce the response time of the beam control device, and reduce the volume of the beam control device to meet the requirement of the common-caliber dual-band phased array antenna becomes a difficult problem which must be solved by the beam control device. The control precision of the beam control device is the result of the combined action of the beam control device and the phase shift unit, because the phase shift quantity of each unit of the T/R component and the phase shift control signal have initial phase inconsistency or the phase shift characteristics of each unit under different frequency and temperature conditions are different, in order to obtain higher phase control precision, the beam control device needs to compensate and adjust the phase shift control quantity, the beam control device needs to compensate the nonlinearity and individual difference of the phase shift control unit and the difference under different frequency and temperature conditions, and the beam control device needs to take into account both the initial phase adjustment and the directional diagram forming two circuit functions.
