step 8) if it exceeds the number of transmission links of array antenna, then set transmission link number NumCh as 1, add the loop variation with 1, phase calibration weight Wphase(loop)=w(1), w(2), . . . , w(n) is the phase calibration weight corresponding to the maximum value of power of transmission signal;
step 9) judge whether the current calibration weight Wphase(loop) is same as the calibration weight Wphase(loop\u22121) of last time, if they are same, then it means the phase calibration of transmission link successes, modify the calculated phase calibration weight using the first line vector Vbutler,1 of the inverse matrix of the transmission link’s equivalent weight coefficient matrix for Bulter matrix, that is, WPHASE=WPHASE(loop)Vbutler,1, the phase calibration is end;
step 10) if they are not same, then judge whether the loop variation loop is larger than the maximum loop number M, if it is true, then prompt the failure of phase calibration of transmission link, the phase calibration is end, otherwise loop back to step 3).

step 5) perform the AD conversion for above power signal, get the power of the transmission signal, and store this power value;
step 6) add the phase calibration weight of NumChth transmission link with 1, judge whether the phase calibration weight of NumChth transmission link is less than or equal to the value range of phase calibration weight, if it is less than or equal to the value range, then calibrate the phase of NumChth transmission link, then loop back step 2);
step 7) if it is larger than value range, then judge whether the variation range of transmission signal power can meet the request, if it can not meet the request, then prompt the failure of the phase calibration of NumChth transmission link;
step 8) if it meets the request, then record the phase calibration weight corresponding to the maximum value of transmission signal power, then add the transmission link number with 1, loop back to step 2).
