The Synchronization Transceiver Design and Experimental Verification for the LuTan-1 SAR Satellite

Sensors, 2020
The deviation between the two oscillators in BiSAR systems will cause a residual modulation of echo signal. Therefore, the phase synchronization is an important issue that must be addressed for BiSAR systems.

Squint Model InISAR Imaging Method Based on Reference Interferometric Phase Construction and Coordinate Transformation

Remote Sensing, 2021
The imaging quality of InISAR under squint geometry can be greatly degraded due to the serious interferometric phase ambiguity (InPhaA) and thus result in image distortion problems.

Microwave Remote Sensing Of Soil Moisture [PDF]

SPIE Proceedings, 1984
Because of the large contrast between the dielectric constant of liquid water and that of dry soil at microwave wavelengths, there is a strong dependence of the thermal emission and radar back-scatter from the soil on its moisture content. This dependence provides a means for the remote sensing of the moisture content in a surface layer approximately 5
