Ionospheric scintillation and total ionospheric electron content monitoring device

Abstract

The invention discloses an ionospheric scintillation and ionospheric electron total content monitoring device. The device includes: a multi-band satellite signal receiving antenna for receiving satellite signals passing through the ionosphere to the ground; a multi-band ionospheric scintillation and ionospheric total electron content integrated monitoring receiver for obtaining satellite signals and monitoring satellite signals Perform high-speed sampling, separate and extract the impact information of satellite signals when passing through the ionospheric inhomogeneity, and simultaneously calculate and output the ionospheric scintillation index and / or ionospheric total electron content in multiple frequency bands in real time according to the impact information. With the help of the technical solution of the present invention, the two important parameters of multiple frequency bands, ionospheric scintillation and TEC, can be monitored in real time on the same device at the same time, and multiple frequency bands can be simultaneously provided for various space information systems (especially military systems) in my country. Scintillation forecast and early warning service.

Description

technical field [0001] The invention relates to the field of ionospheric physics research, in particular to a multi-band ionospheric scintillation and ionospheric total electron content integrated monitoring device. Background technique [0002] About 60 to 1,000 kilometers above the earth's ground is the ionosphere, and there is an ionization heterogeneity in the ionosphere, which will have an important impact on the ground-air link signal passing through it. When the radio signal passes through the ionosphere, the amplitude and phase of the signal carrier will produce short-period irregular changes. This change is called ionospheric scintillation phenomenon; satellite-to-earth radio signals will also cause delays when passing through the ionosphere. The effects of ionospheric scintillation and delay will bring down the performance of ground-to-air radio systems such as satellite communications, navigation, and radar monitoring. In severe cases, the system signal may be int...
