System and method for improving information receiving efficiency of PAF data processing terminal

Abstract

The invention discloses a system and method for improving the information receiving efficiency of a PAF data processing terminal, and belongs to the related technical field of signal transmission, the system comprises a preprocessing front end and a signal processing rear end, and a frequency mixing device is arranged between the preprocessing front end and the signal processing rear end; the preprocessing front end comprises a receiver device, a signal processing device and a signal channel; the signal processing device obtains an observation signal from the receiver device; the processing device is connected with the signal channel; a balance differential network is arranged among the plurality of signal channels; the signal channel is connected with the signal processing rear end; the precision and the accuracy of the observation signal are greatly improved through the frequency mixing device and the synchronous signal of the standard clock module; the loss of the observation signals of different frequency bands in the transmission process is almost the same through the balance differential network, and the folded signals can reflect the shapes of the observation signals more accurately.

Description

technical field [0001] The present invention relates to the technical field related to signal transmission, and more specifically relates to a system and method for improving the efficiency of receiving information by a PAF data processing terminal. Background technique [0002] Radio astronomy is a discipline that studies astronomical phenomena by observing radio waves from celestial bodies. The four major discoveries in astronomy in the 1960s: quasars, pulsars, interstellar molecules, and cosmic microwave background radiation were all obtained through radio observations. of. Since the electromagnetic wave signals radiated from distant celestial bodies are extremely weak, it is necessary to use large-scale radio telescopes with high sensitivity for observation. [0003] A pulsar is a type of neutron star rotating at high speed. It is formed when a massive star collapses under its own gravitational force at the end of its evolution. The synchrotron radiation emitted by the ...

Problems solved by technology

[0005] To compensate for this effect, the usual method is to transform the received time-domain signal into the frequency domain, and divide it into several channels according to the frequency spectrum. Each channel contains component signals of a specific frequency range. The signal is delayed (or advanced) so as to achieve the effect of dispersion elimination; but transmission in different channels will cause different degrees of loss, so it will cause damage to the formation of the synthesized pulsar signal; therefore, the development of a method that can overcome existing defects The device is a problem that those skilled in the art need to solve urgently
