Evaluation system and method for reducing observation error based on radio astronomical instrument

Abstract

The invention belongs to the technical field of radio astronomical instruments, and discloses an evaluation system and method for reducing observation errors based on a radio astronomical instrument. The evaluation system for reducing the observation error based on the radio astronomical instrument comprises: a signal acquisition module, a signal preprocessing module, a central control module, an error evaluation module, a correction fitting module, a data storage module, an update display module, a local area network, a computer, a frequency spectrograph, an observation device, an interference module of a normally open contact, a signal transmitting and receiving antenna of the normally open contact, and a signal source. According to the evaluation system for reducing the observation error based on the radio astronomical instrument provided by the invention, the observation values under the influence of interference factors are analyzed by testing and evaluating the reduced observation values of the radio astronomical instrument in combination with the technical indexes and observation requirements of a radio astronomical observation system, therefore, the method has important influence significance for narrowing observation evaluation and calculation of a radio astronomy observation system, and has important significance for the progress of radio astronomy.

Description

Technical field [0001] The present invention belongs to the technical field of radio astronomy instrument, in particular, it relates to systems and methods for evaluation of measurement error reduction based radio astronomy instrument. Background technique [0002] Currently, radio astronomy instruments are basic equipment observation and study of radio waves from the celestial bodies can be measured radio strength, spectral and polarization equal amount of objects, comprising a collecting directional antenna radio waves, amplifies the high sensitivity of the receiver radio signal, the information field notes, processing and display systems. 1960 astronomy has made four very important discovery: pulsars, quasars, cosmic microwave background radiation, interstellar organic molecules, known as the "four great inventions." Radio astronomy instruments to receive and send signals astronomy star field of play and the discovery of its important role. But try again accurate measurement i...

Problems solved by technology

However, no matter how accurate the measurement is, there will be errors. Therefore, scientists have been studying the error calculation of observation values, using various formulas for calculation, and have been trying new algorithms to continuously optimize the observation error. calculate

[0003] Through the above analysis, the problems and defects of the existing technology are: the existing radio astronomy instruments have large errors, resulting in inaccurate final measurement results
