It is to say, once occurring when all can not complete millimeter wave antenna centering by normal operating, it will be difficult to judge that its reason is because right
Employed in data existing problems, be also because signal transmission environment existing problems etc..
By analysis above, for avoiding because orientation is excessive and cause antenna pair not set up towards error, use and cancel compass
Method.
Certainly, in this case, the distance between 2, also determine the effective depth difference scope between 2 big
Little.Only in the range of this, the method just can realize two websites antenna the most all without any the other side's positional information time certainly
Dynamic centering.
Owing to the communications distance of millimeter wave is generally at about 20KM, signal lobe is typically at 1～3 °.Ground
Two websites, are defined herein as A and B point, as follows, the antenna pair that A to be realized, B are 2, theoretically, if it is known that
Its position coordinates each other, difference in height, antenna towards, just can carry out two antennas pair by adjusting antenna attitude each other
In.
For realizing this purpose, it is necessary to website A and website B must obtain the position coordinate data of the other side's website, antenna points to
Data and antenna horizontal reference data.And data exchange to be carried out, with know both antennae position and towards.
(1) slave site antenna pitching angle adjusts and rotates；
According to known home site position coordinate data,
From the point of view of centering principle described above and process, centering to be realized between two websites, for slave site, most critical and
It is important to obtain the relative height differential of principal and subordinate's site location.The accuracy of these data determines the accuracy of this pattern centering.
And the altitude information of the height of home site and slave site all can be entered by GPS or other height detection means (such as atmospheric pressure)
Row detection is revised.
Patent of the present invention proposes a kind of novel millimeter wave centering method, it is characterised in that: two millimeter wave antennas are by two millis
The mode that Metric wave aerial is at the uniform velocity rotated by certain differential is to obtain antenna pair information and to realize centering.
Key step includes:

(2) another millimeter wave website 2 is in millimetre-wave attenuator range areas, according to the position being the millimeter wave website 1 first obtained
Information (as positioned by GPS or Big Dipper network for location), including latitude and longitude coordinates and the elevation information of website；In conjunction with our station
The positional information of some position, can calculate distance and the difference in height of two websites；Thus calculate the sky of website 2
The luffing angle that line should adjust；
(3) based on website 2 angle of depression angle calculation value, by drive and control of electric machine, this antenna elevation angle is adjusted to this angle value, and
Start at the uniform velocity to rotate by given speed；Its rotary speed becomes certain difference with the sky line options speed of website 1；And
Website 2 millimeter wave antenna becomes information emission state, its send content be website 2 positional information (by GPS or
The location information that dipper system is obtained)；
(4) antenna of website 1 and website 2 rotates at different speeds, in some moment, and two antennas meeting centerings, now, stand
The center support system of point 1 by the detection presence or absence of antenna receiving signal and power, and according to the rotational angle in moment at that time
Position, just can determine that its own antenna institute right orientation and towards；
(5) website 1 stops operating, and starts to launch information；
(6) website 2 antenna continues to rotate a circle after website 1 is fixing, and receives what website 1 was sent in this swing circle
Handshaking information, the presence or absence of website 1 handshake that website 2 is received according to antenna and intensity, in conjunction with antenna corner,
