The object of the present invention is achieved like this, and it comprises that step is as follows:
At first carry out coarse alignment:
1. antenna position information collection, our station and distance station utilize the GPS receiver to carry out the antenna position information collection, and the antenna position information of our station antenna position information and distance station is delivered to low frequency cell;
2. calculate communication party's parallactic angle, low frequency cell calculates the azimuth of communication link by the antenna position information of the distance station of the our station antenna position information that obtains and input;
3. determine the angle that antenna should change, according to low frequency cell calculate communication party's parallactic angle and the aerial angle of electronic compass indication, calculate the angle that antenna should change, give the antenna operation unit by low frequency cell with this information, antenna operation unit controls antenna forwards the angle that should change to, finishes the antenna coarse alignment;
Accurately aim at:
4. preceding antenna alignment of orientation, after finishing the antenna coarse alignment, aim at by antenna and aft antenna before the antenna operation unit controls, antenna keeps the angle of pitch 0 degree before the control, send instruction by low frequency cell and give the antenna operation unit, antenna is being worked as forward azimuth ± 10 ° scope before the control, with 0.2 ° of/second uniform speed scanning, sample to received signal with 1 second speed simultaneously, signal analysis peak signal district according to sampled point, adopt mean algorithm to calculate accurate communication party's parallactic angle, forward preceding antenna to accurate communication orientation;
5. preceding antenna pitching is aimed at, keep accurate azimuth, send instruction by low frequency cell and give the antenna operation unit, antenna is in ° scope of the current angle of pitch ± 3 before the control, with 0.2 ° of/second uniform motion, simultaneously with 1 second speed to signal sampling, according to the signal analysis peak signal district of sampled point, adopt mean algorithm to calculate the accurately communication angle of pitch, forward preceding antenna to accurate communication pitch position;
6. aft antenna is followed aligning, sends instruction by low frequency cell and gives the antenna operation unit, and antenna operation unit controls aft antenna forwards the azimuth and the angle of pitch identical with preceding antenna to, carries out aft antenna and follows accurate aligning, finishes the scatter communication antenna rapid alignment.
The present invention compares with background technology has following advantage:
1. antenna alignment method of the present invention need not increase any equipment and not need by means of any instrument, only need to increase control program and carry out antenna alignment in low frequency cell and antenna operation unit, so antenna alignment fast, accurately;
2. therefore the present invention has excellent economy owing to only need to increase control program in low frequency cell and antenna operation unit, implements simple, easy to operate.
