A Communication Method for Adaptive Alignment of Dual Directional Antennas

Abstract

The invention discloses a dual directional antenna self-adaptive alignment communication method, which comprises the steps of: step 1), zeroing an azimuth angle and a pitch angle of a ground directional antenna; step 2), zeroing an azimuth angle of an airborne antenna; step 3), calculating a target angle theta 2a of the azimuth angle of the airborne antenna according to GPS position information of the airborne antenna and the ground directional antenna by means of an airborne antenna control module, and calculating a target angle phi 2a of the azimuth angle of the ground directional antenna and a target angle phi 2p of the pitch angle of the ground directional antenna according to the GPS position information of the airborne antenna and the ground directional antenna by means of a ground antenna control module; step 4), and rotating the airborne antenna by means of an airborne antenna servo module, rotating the ground directional antenna by means of a ground antenna servo module, and completing real-time alignment. The dual directional antenna self-adaptive alignment communication method adopts a precise and convenient calibration mode, improves the tedious and complicated calibration mode of the traditional system, and improves the competitiveness of products from the viewpoints of reliability and cost.

Description

technical field [0001] The invention belongs to the antenna field of aviation line-of-sight communication systems, and relates to a dual-directional microwave antenna beam control method, in particular to a program-aligned dual-microwave directional antenna adaptive alignment communication that can be used for ground-air line-of-sight communication Technology, applied in the field of line-of-sight aviation microwave data link transmission. [0002] technical background [0003] With the rapid development of the new military revolution, people have higher and higher requirements for the communication of aviation data link, the speed of data link is getting higher and higher, the communication distance is longer and wider, and the bandwidth is wider and wider. And the available frequency band is limited, and the load power consumption, frequency, and bandwidth limit the related performance of the receiving device and the transmitting device, resulting in a great limitation of t...
