Problems solved by technology
However, the commonly used calculation formulas are relatively complicated, and sometimes some external devices (such as gyroscopes and level meters) are needed. This is suitable for occasions with high tracking accuracy, but it will be too complicated to use in occasions where tracking accuracy is not required. Too high, resulting in waste of resources

Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0030] Such as figure 1 As shown, the present invention provides a kind of simple and easy method for automatic control tracking antenna, and described method comprises the following steps:
[0031] Step 1) Obtain the location information of the moving target: longitude α 1 , latitude θ 1 and elevation h 1 ;
[0032] Step 2) Obtain the location information of the tracking antenna: longitude α 2 , latitude θ 2 and elevation h 2 ;
[0033] Step 3) calculate the azimuth and pitch angle that the tracking antenna should point to the moving target;
[0034] Such as figure 2 As shown, suppose the moving target is point A, the tracking antenna is point B, and the initial position of the tracking antenna points to the North Pole. Without considering the influence of the curvature of the earth, assuming that the distance between point A and point B is c, the ...

The invention provides a simple and practicable method for automatically controlling a tracking antenna The simple and practicable method comprises steps of 1, obtaining motion object positioning information: longitude alpha 1, latitude theta 1 and elevation h1, 2, obtaining positioning information of the tracking antenna: longitude alpha 2, latitude theta 2 and elevation h2, 3 directly calculating an azimuth beta and a pitch angle gamma of the tracking antenna which is pointed to a motion object without considering an earth curvature, and 4, outputting the azimuth beta and the pitch angle gamma to a control rotary table. The control rotary table drives the tracking antenna to run in place through an azimuth motor and a pitch motor to point to a motion object. The simple and practicable automatic control tracking antenna method is simple in calculation, low in complexity and easy to realize.
Description
technical field [0001] The invention relates to an antenna automatic tracking technology, in particular to a simple and easy method for automatically controlling and tracking an antenna. Background technique [0002] For the current real-time transmission system of observation data on high-speed flight platforms to the ground, breakthroughs need to be made in a series of key technical issues, and real-time automatic tracking of moving targets by ground receiving antennas is one of the key technologies. Due to the limitations of volume, weight and power consumption, it is impossible to use large-diameter high-gain directional antennas for small flying platforms, and omnidirectional antennas are generally used. In order to ensure the establishment of the data communication link, the ground receiving system must adopt a high-gain directional antenna. The disturbance, motion trajectory and distance of the flying platform all affect the real-time tracking of the ground receiving...
