| Abstract: | The beam steering of the 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 given in the paper. |
