The invention provides a high-efficiency and high-precision calibration method for a double-reflector antenna system, and aims to efficiently and precisely calibrate a long-distance (20-50 meters) double-reflector antenna system under the condition that electric axis alignment cannot be carried out. A pure mechanical mode is adopted for calibration, a central coordinate system is established at a central focus of the double-reflector antenna system, tangent plane alignment parameters are increased, the influence of a site on beam radiation is reduced, subsequent system joint debugging difficulty is reduced, and efficient microwave energy transmission at a long distance of 20-50 meters is realized.
Description
technical field [0001] The invention relates to a method for calibrating a double-reflector antenna system. Background technique [0002] As a new type of energy transfer, wireless energy transfer technology can transmit energy wirelessly over long distances without any guided wave, the transmission speed is the speed of light, and the energy transfer can be flexibly changed by controlling the beam direction. Its working process is that the microwave source converts DC energy into microwave energy, and sends it to free space through the reflector antenna. The beam replaces the high-voltage line to realize remote energy transmission. At the user end, the microwave energy is also received through the reflector antenna and realizes DC energy conversion output. It can be used in solar power plants, deep space exploration and other application fields. [0003] In the radio wave radiation wireless energy transfer technology, the transmitting antenna and the receiving antenna form...
