Abstract

The invention belongs to the technical field of sea detection radars, and discloses an ocean and ionosphere integrated detection high-frequency radar system and a control method thereof. The ocean and ionosphere integrated detection high-frequency radar system comprises a display control platform, a time schedule controller, a comprehensive signal generator, an ionosphere detection subsystem and an ocean information detection subsystem. According to the invention, according to the principle of a high-frequency ground wave radar and an ionosphere vertical measuring instrument, a novel ocean-ionosphere information integrated detection high-frequency radar system is designed, ocean-ionosphere information synchronous acquisition is achieved, and data support is provided for scientific research such as near-earth ocean-atmosphere physical operation law and principle analysis; and by designing a unified time schedule controller and waveform parameters synchronous with each other, synchronous acquisition of ionospheric vertical measurement and ocean information is realized, mutual interference between the ionospheric vertical measurement and the ocean information is avoided, non-interference between ionospheric vertical measurement and ocean information acquisition is ensured, and ionospheric information and ocean information can be acquired synchronously.

Description

technical field [0001] The invention belongs to the technical field of sea detection radar, and in particular relates to a high-frequency radar system for integrated detection of sea and ionosphere and a control method thereof. Background technique [0002] At present, in the vast and infinite world where human beings live, the ocean and the ionosphere are two major components that are closely related to human existence. Therefore, scientists have made unremitting exploration and research in these two scientific fields for a long time, and have made brilliant achievements. research results. With its unique system advantages, HFSWR has been widely used in marine over-the-horizon target detection and sea state remote sensing. At the same time, HFSWR ionospheric detection research has also made breakthroughs in recent years. Therefore, people hope to further expand the research on the dynamic relationship between the ocean and the ionosphere on the basis of the existing HFSWR ...
