Description

technical field [0001] The invention belongs to the field of ionosphere research and application, in particular to an ionosphere region reconstruction method in the field. Background technique [0002] At present, the regional scope of my country's ionospheric environment research is mainly concentrated in the local territory, and the development of ionospheric cognition in overseas and remote seas is slow due to the lack of effective detection methods and reconstruction technologies. In recent years, with the development of high-frequency backscatter detection technology, real-time and rapid acquisition of ionospheric information over a large area overseas can be achieved by deploying high-frequency backscatter detection equipment in China. High-frequency backscatter detection technology is divided into two types: wide beam detection technology and narrow beam detection technology. The wide beam detection technology is mainly based on a single antenna for detection, and the...
