GNSS-R (Global Navigation Satellite System-Reflection) sea surface information detection system

Abstract

The invention discloses a GNSS-R (Global Navigation Satellite System-Reflection) sea surface information detection system. The GNSS-R sea surface information detection system comprises a plurality of sets of detection equipment F, a far-end server D and a data display module E, wherein the plurality of sets of detection equipment are arranged at different positions and are used for detecting sea surface information of different regions; each set of detection equipment comprises a signal receiving module A, a signal processing module B and a data transmission module C; each signal receiving module A is used for receiving a direct signal emitted by a GNSS satellite and a reflection signal reflected by a sea surface; each signal processing module B is used for processing the direct signal and the reflection signal and inverting the sea surface information of the detected regions; and each data transmission module C is used for transmitting the detected sea surface information to the far-end server D in real time. By using the plurality of sets of detection equipment F, a sea surface condition of a wide sea area can be monitored in real time.

Description

technical field [0001] The present invention relates to a GNSS-R (Global Navigation Satellite system-Reflection) sea surface information detection system, specifically a terminal that receives direct signals and reflected signals from satellites and performs corresponding processing on the signals, and can display sea surface conditions in real time , belonging to the field of remote sensing application technology. Background technique [0002] GNSS not only provides users with precise navigation, positioning and precise time, but also provides global microwave signal sources with high stability and security all day and all day. Since the 1990s, GNSS-R technology is a new branch gradually developed in the field of GNSS, and it is one of the research hotspots in the field of remote sensing detection and navigation technology at home and abroad. This technology receives and processes the navigation satellite signals reflected by the ocean surface through shore-based, airborne...

AI Technical Summary

Problems solved by technology

Due to the limitations of monitoring methods, immediate response and information sharing cannot be achieved, providing direct and efficient services for offshore production and construction

Moreover, the current observation methods can only detect the status of the monitoring points. For regional detection, we can only rely on the traditional rough monitoring method of replacing the area with points, which cannot accurately describe the changes in the actual sea conditions in the area.
