Abstract

The invention discloses a satellite-borne very low frequency solar radio observation system. The system is used for observing a low frequency solar radio signal of 20-100 MHz. The system comprises three electric field sensors, three sets of analog receivers, a data acquisition and processing module,a time frequency module, a power module and a storage module, wherein the three electric field sensors are respectively connected with the three sets of analog receivers; the three sets of analog receivers and the time frequency module are respectively connected with the data acquisition and processing module; the data acquisition and processing module is connected with the storage module; and the data acquisition and processing module and the three sets of analog receivers are respectively connected with the power module. The system disclosed by the invention can judge the motion of coronal projectiles, predict and anticipate the future space weather event.

Description

technical field [0001] The invention relates to a space-borne very low frequency solar radio observation system, which is suitable for 100KHz-20MHz frequency band solar radio observation based on a satellite platform, and can detect coronal ejection material CME in three dimensions by using a space orthogonal three-dimensional electric field sensor Electromagnetic waves, and then determine the direction of motion of the CME. Background technique [0002] The sun is the celestial body most closely related to human production and life. Its light and heat warm the earth and provide the proper environment necessary for all life activities on the earth. The sun is a very active celestial body, and there are often violent activities and eruptions. A large number of observational and theoretical studies have been carried out on a large number of solar eruptions, including flares, coronal mass ejections (CMEs), obscura / prominence eruptions and jets, etc. Among them, flares and cor...
