Research Interests:
GNSS remote sensing, including:
1. GNSS occultation technology. This technique can observe global neutral atmosphere and ionosphere. The principle of the technique is to install the GNSS receiver on mountain, plane or LEO satellite and do limb sounding for GNSS satellite. When the radio signal spread through the atmosphere and ionosphere, the signal path will be bended because of the variety of refractivity, from which we can retrieve the atmospheric refractivity, pressure, density, temperature, and water vapor, also we can obtain the electron density in the ionosphere. It can operate all weather with long-term stability and global coverge. And its product has high precision. Occultation sounding is the supplement of traditional measurements. The occultation data of global distributed will greatly promote the precision of numerical weather prediction and research on the space near the Earth, and in addition, it can be applied to study on climate and global change. The occultation technique is of great importance to research on atmosphere model and data assimilation. The GNSS radio occultation technique has shown a great future in the field of climate, meteorology, ionosphere, and geodesy.
2. GNSS-R remote sensing. GNSS-R remote-sensing has generated considerable attention by researchers and institutes in recent years, It is an offspring of bistatic radar in which only receivers need to be deployed on specific platform(coastal, airborne orspaceborne), GNSS-R Receiver measuring sea or land reflected signal waveform which contains information of sea or land surface characteristics. GNSS-R remote sensing technique can be used to extract ocean surface geophysical information, such as sea surface wind field, sea surface height and significant wave height , detect sea ice , tsunami monitoring and early warning, mesoscale ocean dynamic environment studying and measurement of land surface soil moisture.
