A method that can eliminate signal interference caused by mobile phone signals to radio telescopes

Abstract

The invention discloses a method capable of eliminating signal interference generated by mobile phone signals to radio telescopes. The system defaults to configuring the latitude and longitude of each radio telescope (i=1, 2,...,n); the mobile phone and each radio telescope are to be shut down to specify a silent zone Range and number (usually set to three restricted areas, core area, and quiet area); calculate the user's current latitude and longitude with the latitude and longitude of each radio telescope, and the calculated distance is Distance uti (i=1, 2,..., n); Use the distance algorithm to determine the distance between the user and the nearest radio telescope Distance ut ;Determines whether the user is within the quiet zone range of a radio telescope. The beneficial effect of the invention is that it can reduce the signal interference caused by the mobile device to the radio telescope, so as to obtain more real observation data, thereby providing more reliable data guarantee for the experiment.

Description

Technical field [0001] The invention belongs to the field of radio technology, and relates to a method capable of eliminating signal interference from a mobile phone signal to a radio telescope. Background technique [0002] The birth of radio astronomy stems from an accidental discovery. In order to explore the radio interference that may affect the telephone business across the Atlantic, Yansky, an engineer at Bell Labs in the United States, built a "carousel" antenna whose base can be rotated to " Listening to the "noise" from different directions in the sky, after several months of observation, Youngs found and confirmed radio radiation from the center of the Milky Way at a frequency of 20.5 MHz and a wavelength of about 14.5 meters in 1932. The discovery was officially published in 1933. This marked the birth of radio astronomy, and all previous astronomical observations were limited to visible light. [0003] The initial start and development of radio astronomy technology be...

[0004] Since the 1980s, the VLBI network in Europe, the VLBA array in the United States, and the space VLBI in Japan have been put into use one after another. This is a representative of a new generation of radio telescopes, and their sensitivity, resolution and observation band have greatly surpassed previous telescopes. , among them, the United States' Very Normal Baseline Array (VLBA) is composed of 10 parabolic antennas, spanning a distance of 8,000 kilometers from Hawaii to St. Croix, its precision is 500 times that of the Hubble Space Telescope, and it is the same as the human eye 600,000 times, the resolution it achieves is equivalent to a person standing in New York reading a newspaper in Los Angeles. Today’s radio resolution is thousands of times higher than other bands, which can reveal the core of radio celestial bodies more clearly; the development of synthetic aperture technology The radio telescope has been successfully equipped with convenient imaging capabilities, which is equivalent to a camera working in the radio band. In order to receive signals from the universe more clearly, scientists suggest that the radio telescope be moved to space. On February 10, 2015, scientists It is planned to send information from the earth to the universe, hoping to actively contact other life in the solar system and obtain their signals. Astronomers will send signals to hundreds of distant galaxies through radio telescopes, hoping to obtain groundbreaking discoveries. However, radio telescopes have Are susceptible to interference from radio stations (stations), facilities that radiate electromagnetic waves (mobile phones, TVs, microwave ovens, induction cookers, cars) or any other daily devices that emit radio waves
