Ocean waves near Hurricane Josephine from SIR-B [PDF]

Radar images of ocean surface waves near hurricane Josephine were acquired with the Shuttle Imaging Radar-B (SIR-B) system on October 12, 1984. Fast Fourier transform analyses of the images were performed along most of the 600-km image track.

Radar Images of Leaks in Building Elements

Energy Procedia, 2015
AbstractThrough leakage in the building envelope there is a penetration of air, water vapor and particles. The degree of leakage of air can be quantified by existing methods. However, the location of adventitious openings is often not known. In order to overcome the limitations in existing methods, a non-contact and non-destructive method based on ...

Design, Simulation, and Fabrication of High‐Performance Metamaterial Absorber for EMI Mitigation and THz NDT/Imaging Applications: A Shape‐Preserved GHz‐to‐THz Transition Approach

Advanced Theory and Simulations, EarlyView.
A novel metamaterial absorber is designed, simulated, and validated for both 5G mmWave and THz applications, achieving >95.8% and 90% absorption, respectively. Its polarization‐insensitive, scalable design enables applications in THz NDT, imaging, and EMI shielding.

A Novel Method to Identify the Spaceborne SAR Operating Mode Based on Sidelobe Reconnaissance and Machine Learning

Remote Sensing
Operating mode identification is an important prerequisite for precise deceptive jamming technology against synthetic aperture radar (SAR). In order to solve the problems of traditional spaceborne SAR operating mode identification, such as low ...

L-band radar sensing of soil moisture [PDF]

The performance of an L-band, 25 cm wavelength imaging synthetic aperture radar was assessed for soil moisture determination, and the temporal variability of radar returns from a number of agricultural fields was studied.

Multistatic radar imaging of moving targets

2010 IEEE Radar Conference, 2010
We develop a linearized imaging theory that combines the spatial, temporal, and spectral aspects of scattered waves. We consider the case of fixed sensors and a general distribution of objects, each undergoing linear motion; thus the theory deals with imaging distributions in phase space.

NAD+‐Boosters Improve Mitochondria Quality Control In Parkinson's Disease Models Via Mitochondrial UPR

Advanced Science, EarlyView.
Treatment of MPTP‐incubated cells with NAD+‐boosters increase the UPRmt/mitophagy‐related mitochondria quality control (MQC). Disturbed plasma UPRmt‐mitophagy‐mediated MQC profiles in PD patient samples. NMN inhibits motor deficit and forestalls neuropathology phenotypes of PD mice, which is required the atf4‐medicated UPRmt pathway.
