Problems solved by technology
[0005] In the above calculation method, the positioning information of both the ground receiving antenna and the moving target needs to be accurate, but in the actual space-ground communication process, when the locator carried on the moving target fails, or the wireless communication link is not smooth, the antenna cannot continue When the positioning information of the moving target is received, the above method will not be implemented due to the lack of data sources, resulting in the antenna not being able to effectively track the moving target, seriously affecting the quality of communication and the accuracy of sending and receiving data

Embodiment Construction
[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0044] A method for automatically controlling the tracking antenna by using the received signal level, said method comprising the steps of:
[0045] Step 1) collecting the received signal level data of the tracking antenna;
[0046] Step 2) Sampling the received signal level data, judging the azimuth according to the sampled value, and turning the azimuth to the motor-driven tracking antenna for running search. If the received signal strength reaches the set range, the search is completed; otherwise, the azimuth angle After the search is completed, point the antenna azimuth to the starting position of the tracking, and enter step 3);
[0047] Such as figure 1 As shown, the step 2) specifically includes:
[0048] Step 201) Set the azimuth direction memory maximum value of the received signal level to be a; and point the antenna to this position; set the azi...

The invention provides a method for realizing automatic control for a tracking antenna by using the received signal level. The method comprises the steps of 1) acquiring received signal level data of the tracking antenna; 2) sampling the received signal level data, carrying out direction judgment according to a sampling value, rotating an azimuth motor to drive the tracking antenna to carry out operation search, and terminating the search if the received signal strength reaches a set range; if not, terminating azimuth angle search, enabling the antenna to point to a track starting position, and getting into a step 3); and 3) carrying out direction judgment according to the sampling value, rotating a pitching motor to drive the tracking antenna to carry out operation search until the received signal strength reaches the set range, terminating the pitching angle search and turning to the step 2) until the antenna tracking process is over. The advantages lie in that searching and tracking can be carried out on a moving target according to the received signal level when the tracking antenna cannot receive positioning information of the moving target.
Description
technical field [0001] The invention relates to an antenna automatic tracking technology, in particular to a method for automatically controlling and tracking an antenna by using the received signal level. 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 t...
