【Abstract】 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 important. The research in this paper firstly explains the on-board processing procedures and describes the simulation method of the on-board environment. Then, combined observation of scatterometer and radiometer, along with altimeter observations are used to realize corresponding method of fast processing on-board the satellites. for the typhoon sea surface wind field and sea surface wave height, 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.更多还原
