Abstract： In order to solve the problem of the beam pointing deviation in phased array antennas， the effect of the radiation pattern of antenna element on array beam pointing is analyzed，and the concept of equalized radiation pattern of antenna elements is proposed.Based on this concept，a fast correction method for beam pointing deviation of phased arry is proposed. Also，the effectiveness and accuracy of the proposed method are validated through two typical examples.

Key words：phased array;beam pointing deviation;correction method
