| Abstract: | Retrieving the soil moisture with multi-path signals of GPS is a newly established research domain in the field of GPS applications in recent years.While,the ground reflection point position determination is of great significance for soil moisture retrieval.According to the space geometric relationships of GPS satellite,antennas of GPS receivers,ground reflection point and the Earth Centre,this paper introduced an algorithm of ground reflection point extraction with multi-path signals of GPS.Furthermore,the ground reflection point and reflected footprint were successfully extracted through Matlab software with experimental data. |
