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 ...

AI Technical Summary

Problems solved by technology

[0005] (1) The existing HFSWR cannot meet the requirements of synchronous acquisition of ocean and ionosphere information and compatible detection of sea targets-ocean-ionosphere in terms of system and function

[0006] (2) The current detection equipment can only detect the ionosphere or ocean information alone, and there will be serious interference between the two different equipment, and they cannot work at the same time

[0007] The difficulty of solving the above problems and defects is: the interference between ionospheric detection and ocean information detection will seriously interfere with the working status of their respective systems, resulting in a sharp deterioration of system performance, failure to work normally or even burning the system

Integrating ionospheric detection with ocean information detection and synchronous detection requires deep integration of the original independent ionospheric dipmeter and high-frequency ground wave radar. The system complexity is high and the solution is relatively difficult.
