The bulk Josephson responce of the d-g-wave cuprate superconductor
, 1997 We consider the implications of the small Fermi surface for the ab-plane microwave absorption. The small Fermi surface results in two superconducting condensates.

UAV-Based SAR-Imaging of Objects From Arbitrary Trajectories Using Weighted Backprojection
IEEE Journal of MicrowavesSynthetic aperture radars (SARs) based on uncrewed aerial vehicles (UAVs) are advantageous in comparison to existing airborne systems. Apart from cost, their main advantage is the flexibility of their flight path.

Microwave Surveillance based on Ghost Imaging and Distributed Antennas
, 2015 In this letter, we proposed a ghost imaging (GI) and distributed antennas based microwave surveillance scheme. By analyzing its imaging resolution and sampling requirement, the potential of employing microwave GI to achieve high-quality surveillance ...

A fiber based diamond RF B-field sensor and characterization of a small helical antenna
, 2018 We present a microwave B-field scanning imaging technique using diamond micro-crystal containing nitrogen vacancy center that is attached to a fiber tip. We propose a pulsed modulation technique, enabling the implementation of a variety of pulsed quantum

Weak target detection technology of passive radar on the navigation satellite signal
The Journal of Engineering, 2019 The passive radar detection system receives secondary reflection signal by the navigation satellite signal. The secondary reflection signal is too weak to detect the target.

Airborne SAR Imaging Algorithm for Ocean Waves Based on Optimum Focus Setting
Remote Sensing, 2019 Ocean waves are the richest texture on the sea surface, from which valuable information can be inversed. In general, the Synthetic Aperture Radar (SAR) images of surface waves will inevitably be distorted due to the intricate motion of surface waves ...
