Pattern Compensation Method for Deformed Active Phased Array Antenna Considering Quantization Error of Phase Shifter

In the service of active phased array antennas (APAAs), the array deformation is inevitable due to the influence of internal and external factors. In this paper, an electrical compensation method considering quantization error is proposed to compensate the change of pattern by changing the phase. The correctness and feasibility of this method are verified by an array with 8x32 elements.
