A Method of Retrieving Tropospheric Refractivity Above Ocean Surface using GNSS

摘要：

　　This paper proposed a method of retrieving tropospheric refractivity above ocean surface using Global Navigation Satellite System,which takes the Final Analysis Data of Global Forecast System as background data,and uses intelligent optimization algorithm to train the inversionnetwork.the method can get tropospheric refractivity profile in any sea area after the zenith tropospheric delay and the atmospheric temperature,humidity,pressure were measured,and it can be used in refraction error correction applications such as radar detection and space tracking.It has less cost than radiosonde but higher precision than traditional empirical model.In addition,it can be used in real time and has higher temporal and spatial resolution.
