On-board Fast Retrieval of Ocean Surface Parameters from Satellite Observations and Featured Applications

Remote sensing plays an important role in retrievals of ocean-related parameters, which are vital in disaster warning. With the development of hardware on-board satellites, real-time retrievals become possible. Among ocean parameters, sea surface wind fields and wave heights are of good importance. The research in this paper firstly explains the on-board processing procedures and describes the simulation method of the on-board environment. Then, for the typhoon sea surface wind field and sea surface wave height, the combined observation of scatterometer and radiometer, along with altimeter observations are used to realize the corresponding method of fast processing on-board the satellites. The results show that the method used in the study can effectively achieve on-board processing. Under the trend of integration of “communication, navigation and remote sensing”, the application of this method will effectively assist automatic real-time decision-making and contribute to disaster warning. The next step of the research will be to achieve more parameters on-board via platform simulation.
