Propagation Effects in Satellite mounted Radar Remote Sensing [PDF]
, 2009 —Active microwave SAR imaging of the Earth’s surface is commonly considered to be of all weather capability. However, as the operating frequencies of SAR-systems are increasing, visible image distortions due to heavy precipitation in SAR-images may ...

Potential of TanDEM-X for forest parameter estimation [PDF]
, 2010 It was demonstrated that interferometric volume coherence is sensitive to vertical forest structure. This is true even for high frequencies as X-band. Resent Experiments demonstrated the potential of X-band to estimate key forest parameters like forest ...

Measurement and Analysis of Radar Signals Modulated by the Respiration Movement of Birds
Applied Sciences, 2022 Once, bird respiration was thought to be responsible for the 10 dB-level fluctuations in the radar signals of birds. Although, recently, many researchers provide evidence against this, there are almost no quantification measurements of the contribution ...
