摘要
针对相控阵天线波束指向受数字移相器量化相位影响而偏离预定指向的问题,从理论上研究了二可能值法对相控阵天线波束指向的影响,并导出有效实用的理论公式.计算结果表明,本文所给出的理论公式是正确和有效的.
The beam steering of phased arrays deviates from the given direction because of the quantization phase in the digital phased shifter. The two-probable number method shown in reference has not been theoretically analyzed. This paper investigated the effect of the two-probable number method on the arrays' beam steering, and an effective formula was developed. The simulating results show the effectiveness and correctness of the formula.
