The invention discloses an airborne ocean microwave remote sensing system utilizing signal sources of a global satellite positioning system. A GNSS-R remote sensor receives and processes navigational satellite collineation and sea echo signals, and outputs Doppler related power and navigational positioning solutions at different time delays; a task monitoring work station carries out sea route planning, remote sensor task state real-time monitoring and data storage management; a data processing and application work station carries out screening, sorting and noise reduction preprocessing on data collected by the remote sensor, and carries out imaging processing and element playback on the processed data to obtain ocean environment monitoring information, such as sea level wind fields, sea level elevations, significant wave heights and the like; and an analog analysis work station provides GNSS-R entire route analog signals. The system effectively solves the problems of lack of ocean microwave remote sensing equipment, low data application timeliness and the like in the prior art, and can provide novel task equipment and a processing analysis means for manned / unmanned airborne platforms, wherein the novel task equipment is available at all weathers and all day long, and has the advantages of multiple signal sources, wide coverage and high space-time resolution.

Description

technical field [0001] The invention relates to a marine microwave remote sensing technology, more particularly, an airborne marine microwave remote sensing system utilizing a global satellite positioning system signal source. Background technique [0002] Marine remote sensing has a large monitoring range, high dynamics, and complex meteorological conditions. Microwave remote sensing has become an important means of remote sensing monitoring of regional and global marine environments. At present, the existing microwave remote sensing methods such as SAR (Synthetic Aperture Radar), scatterometer, and altimeter all use the method of backscatter homogenous observation, the cost of data transmission and reception is high, and the timeliness cannot meet the needs of monitoring applications. The global satellite positioning system not only provides navigation and positioning information for space information users, but also provides a steady stream of L-band microwave signal reso...
