A high-frequency radar system for integrated detection of ocean and ionosphere and its control method

Abstract

The invention belongs to the technical field of sea detection radar, and discloses a marine and ionosphere integrated detection high-frequency radar system and a control method thereof. Controller, integrated signal generator, ionospheric detection subsystem and ocean information detection subsystem. According to the principle of high-frequency ground wave radar and ionospheric vertical measuring instrument, the present invention designs a new type of ocean-ionospheric information integrated detection high-frequency radar system to realize the simultaneous acquisition of ocean-ionospheric information, which is the physical operation law of the near-earth ocean-atmosphere And scientific research such as principle analysis provides data support. At the same time, the present invention realizes the synchronous acquisition of ionospheric vertical survey and ocean information by designing a unified timing controller and designing mutually synchronized waveform parameters, avoiding mutual interference between the two, and ensuring the ionospheric vertical survey and ocean information acquisition. They do not interfere with each other, and can obtain ionospheric information and ocean information synchronously.

Description

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

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.
