A multifunctional processing system and method for observation signals

Abstract

The present disclosure provides a multifunctional processing system for observation signals, including: a signal acquisition and processing front end (100), used to receive observation signals, including a plurality of signal processing boards (110), each signal processing board (110) receiving Observation signals with a preset number of channels and calculation of power spectrum data and baseband data of the observation signals; multifunctional data processing backend (200), used to process power spectrum data and baseband data, including multiple observation mode detection units, to realize Perform corresponding observation mode calculations on the power spectrum data and baseband data; radio frequency signal multiplexer (300), for sending observation signals to corresponding signal processing boards (110); control computer (400), for The number of channels determines the number of signal processing boards (110) to be called, and controls the firmware loading, parameter setting and status monitoring of the signal processing boards (110). In addition, a multifunctional processing method of the observation signal is also provided.

Description

technical field [0001] The present application relates to the technical field of radio telescopes, in particular to a multifunctional processing system and method for observation signals. 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. Radio telescope observations have a wide range of research objectives, including basic scientific research on pulsars, gravitational waves, black holes, star formation and evolution, transient sources, and galaxies. They can also be used in satellite orbit measurements and dee...

Problems solved by technology

If a discrete astronomical terminal is used, each receiver needs to be equipped with an independent observation terminal system, and each observation research needs to develop a separate set of signal processing software for each frequency band of the receiver, which is expensive and requires system reuse. At the same time, observers need to be familiar with the operation process of each system, and the probability of error is high
