Surveying sea surface effect in satellite altimeter-derived wind speed
International Journal of Coastal and Offshore Engineering, 2016 To improve sea surface wind speed in coastal regions, we used nadir satellite altimeter measurements in the Persian Gulf and Arabian Sea. With combining normalized radar cross section for two bands of satellite altimeter measurements and significant wave

A Wind Speed Retrieval Model for Sentinel-1A EW Mode Cross-Polarization Images
Remote Sensing, 2019 In contrast to co-polarization (VV or HH) synthetic aperture radar (SAR) images, cross-polarization (CP for VH or HV) SAR images can be used to retrieve sea surface wind speeds larger than 20 m/s without knowing the wind directions.

Radar cross-section of microstrip antenna on normally biased ferrite substrate
Electronics Letters, 1989 Calculated results for the radar cross-section of a microstrip antenna on a ferrite substrate are presented, and it is shown that the peaks in the RCS can be moved with respect to frequency by changing the magnetic bias field. This effect offers a way of minimising the radar visibility of microstrip antennas and arrays.

Advanced Science, EarlyView.Continuous wet‐spinning of PANI with TeNWs yields a multifunctional microfiber. Oriented TeNWs impose chain alignment and enhance π‐electron delocalization, boosting the Seebeck coefficient to 59.9 µV K−1 for passive temperature sensing (1 K detection limit), while achieving high pH sensitivity (59.25 mV pH−1) and rapid NH3 response (0.96 s).

Calibration and Clutter Cancellation Techniques for Accurate Wideband Radar Cross Section Measurements [PDF]
, 2021 The expected received power is a key design parameter when designing a radar system. The radar’s receiver must be sensitive enough to detect the object of interest without being saturated by the highest received power. The object of interest’s visibility

Advanced Science, EarlyView.ROS‐Responsive H2S Hydrogel (HAPPF) Coordinated Regeneration for High‐Quality Diabetic Wound Repair.A self‐regulating dynamic hydrogel is developed to deliver a fluorogenic H2S donor in response to excessive ROS. Released H2S acts as a master regulator to resolve chronic inflammation (M2 polarization), restore VEGF‐driven angiogenesis, and rebalance ...

Multiscale Circuit Architecture Associated With Memory Dysfunction in Temporal Lobe Epilepsy
Advanced Science, EarlyView.A multiscale precision‐mapping framework reveals that memory impairment in temporal lobe epilepsy arises from the convergence of focal medial temporal pathology, strategic white matter disconnection, and limbic‐centered metabolic network dysfunction.

Multipath Effect on Radar Cross Section Measurements in Natural Environment and Related Correction
, 2022 S.209-214Preliminary results regarding the multipath analysis due to the land surface (grassland and sweet corn) are shown using a X-band radar. The evaluations are based on the measured Radar Cross Section (RCS) variations of a calibrated target taken ...
