Method includes：
Step S501：When the scan angle for monitoring the 2nd array antenna 21 (source array antenna) institute launching beam reaches the 2nd
During the maximum of the scan angle of a 21 launching beams of array antenna, determine Target Aerial Array antenna for the according to the maximum value
3 array antennas 30.
Specifically, by monitoring that the scan angle of 21 launching beams of the 2nd array antenna has reached maximum, institute
With with reference to the direction of Fig. 5 scan angles at this time, (according to according to embodiment two, scan angle is θ at this time to the right1/ 2, then represent scan angle
Direction is positive direction, i.e., to the right).And the 2nd right side of array antenna 21 is the 3rd array antenna 30, accordingly, it is determined that Target Aerial Array
Antenna is the 3rd array antenna 30.
Step S502：When calculating beam switchover to the 3rd array antenna 30, the scan angle of the wave beam.
Specifically, when wave beam is switched on the 3rd array antenna 30 from the 2nd array antenna 20, which sweeps
It is-θ to retouch angle3/2+Δ3.It should be noted that-θ3/2+Δ3The scanning launched in the 3rd array antenna 30 of scope
Between the maxima and minima at angle.Δ3It is a discreet value, is pre-set, therefore Δ3There is scope.
