Real-Time Wireless, Contactless, and Coreless Monitoring of the Current Distribution in Substation Conductors for Fault Diagnosis
Publication Year: 2019, Page(s):1693 - 1700Parallel conductors are found in electrical transmission and distribution systems including large ampacity feeders or loads. However, current unbalance often occurs, especially in alternating current systems. This non-regular current distribution causes overheating and premature aging, facilitating the occurrence of failures. Therefore, a fault diagnosis system is a must, which can be performed by...

Polarization Diversity Technology Research in Passive Radar Based on Subcarrier Processing
Publication Year: 2019, Page(s):1710 - 1719The work in this paper is divided into two parts. The first part is going to investigate the potential benefits of clutter suppression in a polarization filtering technology. The performance of a conventional polarization filter is limited by the complex electromagnetic environment.

Spectrum Sharing in Weather Radar Networked System: Design and Experimentation
Publication Year: 2019, Page(s):1720 - 1729Weather radar networked system (WRNS) is composed of multiple weather radars that transmit a radio signal and receive an echo signal reflected by weather targets. In the current form of WRNS, each radar exploits a different non-orthogonal frequency band, which leads to inefficiency in frequency usage.
