Title:
OCEAN OBSERVATION METHOD AND SYSTEM BASED ON ACCOMPANYING FLIGHT OF TWO SATELLITES RESPECTIVELY CARRYING INTERFERENCE IMAGING ALTIMETER AND LASER RADAR
Document Type and Number:
WIPO Patent Application WO/2022/171202
Kind Code:
A1
Abstract:
The present application relates to an ocean observation method and system based on accompanying flight of two satellites respectively carrying an interference imaging altimeter and a laser radar. The ocean observation method comprises: an observation step, which is configured to observe, in an operation orbit, an ocean phenomenon by means of a first satellite and a second satellite which perform accompanying flight in the same operation orbit, wherein the first satellite performs ocean surface height observation by means of carrying an interference imaging altimeter, and the second satellite performs atmosphere and ocean profile observation by means of carrying an ocean profile laser radar; and a data processing and transmission step, which is configured to receive, by means of the first satellite, atmosphere and ocean profile observation data sent by the second satellite, and send, to a ground station, the atmosphere and ocean profile observation data and ocean surface height observation data from the first satellite, and which is configured to process, by means of the ground station, the ocean surface height observation data and the atmosphere and ocean profile observation data, so as to obtain an observation result. By means of the present application, the problem of realizing, at a low cost and low risk, the wide-swath and sub-mesoscale observation of an ocean and the remote sensing detection of a near thermocline of the ocean is solved.
