Embodiment one
Referring to FIG. 1, the embodiment of the present application one provides a kind of satellite capture method based on multiple beamwidth, it is applied to phase
Control array antenna system, comprising:
Step 101: control phased array antenna system issues beam angle and exists more than or equal to the first electromagnetic wave of first angle
It is scanned within the scope of predetermined angle according to the first predetermined manner with the first stepping, obtains the first scanning corresponding with scanning every time
As a result, wherein first stepping is the angle more than or equal to the first width；
The beam angle can refer to: when aerial radiation goes out electromagnetic wave signal, greatest irradiation direction two sides, and radiation
Power declines the angle of the both direction of 3dB.Therefore, the beam angle in this step is more than or equal to the first electromagnetism of first angle
Wave can refer to the wider wave beam of beam angle, for example, when the first angle is 3db, what phased array antenna system issued
Signal beam can be set to the wide wave that width is greater than 3db.
And the stepping in the embodiment of the present application, when can refer to that the phased array antenna system is scanned operation, antenna side
To the angle or radian moved every time or compared to the distance, etc. of prior location, exist as long as antenna direction can be characterized
It is scanned the parameter of the degree moved every time when operation, all can serve as the stepping.Stepping in the embodiment of the present application can
Included angle to refer to using the central point of antenna array as origin, when antenna direction and preceding single pass between antenna direction.
Therefore, first stepping is the angle more than or equal to the first width, can refer to the biggish wide angle of move angle, for example,
When first width is 3.5db, first stepping can be set to 4db.
The predetermined angle range can be user anticipation satellite may direction, in practical operation can by with
Family self-setting, or by systemic presupposition.
That is, in the implementation procedure of this method, can first using wide wave to the possible place orientation of satellite into
The scanning of row polarizers of big angle scope, while biggish stepping, that is, first stepping are used in the polarizers of big angle scope, it carries out thick
It slightly scans, thus to obtain the scanning with the multiple satellite feedback signals correspondingly of the mutiple antennas direction in the polarizers of big angle scope
As a result, namely described first scanning result.
Coarse scan is carried out due to using larger stepping in this step, this step is when actually executing Shi Suohua
Between it is less.
Step 102: determined based on first scanning result include at least three most strong feedback signals the first range；
Due to obtaining the scanning knot with mutiple antennas direction multiple satellite feedback signals correspondingly in step 101
Fruit namely first scanning result.In this step, it can determine that signal strength is most strong from this multiple scanning result
Multiple satellite feedback signals, further determine that out first range including these most strong feedback signals, certainly, described
One range is smaller than the predetermined angle range.Thus play the role of further reducing satellite direction range.
Step 103: controlling the phased array antenna system and issue the second electromagnetism that beam angle is less than or equal to second angle
Wave is scanned in first range with the second stepping, obtain the second scanning result, wherein second stepping be greater than
Equal to the angle of the second width, and second width is less than or equal to first width；
Beam angle in this step is less than or equal to the second electromagnetic wave of second angle, can refer to that beam angle is relatively narrow
Wave beam, for example, the signal beam that phased array antenna system issues can be set to width when the second angle is 2.5db
Narrow wave less than or equal to 2.5db.
Similarly, in the implementation procedure of this step, biggish stepping can be further used in first range
It is exactly that second stepping carries out coarse scan, but second stepping is less than or equal to the first stepping, so that the scanning of this step
Operation may be more careful compared in step 101, and since the beam angle of use is relatively narrow, this step is obtained multiple
Scanning result precision is more accurate compared in step 101.
In other words, this step can obtain and the multiple satellites correspondingly of the mutiple antennas direction in first range
The more careful and more accurate scanning result of feedback signal --- second scanning result.Similarly, it is still used in this step
Larger stepping is scanned, therefore this step takes time also still can be less when actually executing.
Step 104: determined based on second scanning result include at least three most strong feedback signals the second range；
Similarly, in this step, it can also determine that signal strength is strongest multiple from second scanning result
Satellite feedback signal further determines that out second range including these most strong feedback signals, certainly, second range
It is smaller than first range.Thus play the role of further reducing satellite direction range.
Step 105: control the phased array antenna system using a line in second range as center line, it is phased
The central point position of array antenna front obtains third and sweeps to be scanned within the scope of the cone on vertex according to third stepping
Retouch result, wherein the third stepping is the angle less than or equal to third width, and the third width is less than or equal to described the
Two width；
Since the actual emanations direction of antenna beam is similar to cone, this step passes through in second range
Smaller cone range is taken to be scanned operation, then the number that operation antenna beam carries out motion scan is less, mobile journey
Degree is smaller, therefore can get strongest satellite feedback signal with higher efficiency.And it uses be less than or equal in this step
The third stepping of third width, the step precision of scanning accuracy than before is higher, therefore can obtain further accurate
Scanning result, that is, the third scanning result.
Since second range has been the range further reduced, and further it is reduced into more in the second range
Small cone scanning range, therefore even if this step is smaller using stepping, the narrower mode of beam angle is scanned, institute
Time spent will not be too long.
Certainly, also there are many scan methods for being directed to cone range in the prior art, for example, being determined with preset algorithm
Then the cone bottom surface is considered as preset interval in the multiple of matrix-style arrangement by the basal surface position of the cone range
Point, further successively sequence is scanned towards these directions.It can also be by the point on the cone bottom surface according to suitable
Clockwise counterclockwise carries out spiral scan, etc..It can be seen that in the prior art there are many scanning mode, user can be with
Self-setting as needed.
Step 106: determined based on the third scanning result include most strong feedback signal third range, and will be described
Third range is as satellite region；
Wherein, the scanning result is the parameter value to characterize the satellite feedback signal strength received.
That is, this step can be from the smaller satellite location determined --- it is used within the scope of the third
The higher mode of scanning accuracy and in the scanning result determined, further the orientation where strongest satellite feedback signal determines
Orientation where more accurate satellite out.

It is scanned within the scope of predetermined angle and obtains the first scanning result, quickly determine that the substantially location of satellite is the first model
It encloses；Then it is scanned using the big stepping in first range of narrow wave and further determines that out more accurate satellite location
For the second range；Smaller cone range is further taken to carry out in second range using narrow wave and small stepping again accurate
Scanning, so that it is determined that going out most accurate satellite region.As it can be seen that the technical solution in the embodiment of the present application evaded it is traditional
The drawbacks of scanning of inertial navigation device and mechanical scan, orientation where very efficiently quickly can determining satellite have and improve
The technical effect of satellite scan efficiency and scanning result precision.
Further, in a step 101, it is described within the scope of predetermined angle according to the first predetermined manner with the first stepping into

In the integer for being equal to 1；
It is described using the N group vertical plane scanning result as first scanning result, comprising:
Using N group M and/or Q angle scanning result of N group as first scanning result.
Since the strongest satellite of feedback signal is generally in the top position of antenna array, and substantially very little probability can be located
In the orientation flattened out with antenna array, therefore in order to reduce unnecessary scanning range, scan efficiency, the application are further increased
Technical solution in embodiment can only for horizontal by 30 ° of angles to horizontal by 360 ° of models within 90 ° of angles
