Accurate Far-Field Measurement of Wide-Angle Scanning Phased Array Antennas

Autor: Nanjing Coral Electronic Equipment Co. Ltd, Nanjing, China, Xianbao Zheng, Hongjun Tang

Publikováno v: Applied Computational Electromagnetics Society. 36:1224-1228

This paper presents a new approach to the accurate determination of the far-field (FF) pattern of wide-angle scanning phased array antennas (PAAs) that uses planar near-field (NF) technology. When PAAs are engaged in wide-angle scanning, a finite sca

Publikováno v: Orthopaedics & Traumatology: Surgery & Research. 106:109-115

Introduction Ilio-sacral screw fixation has been used for sacral fractures and sacroiliac joint dislocations. However, it is associated with significant complications including screw loosening with backing-out and loss of reduction. Trans-sacral scre

Rotating Beamforming in the Frequency Domain for an Incomplete Microphone Array

Autor: Wei Ma, Wei Zhou, Mengxuan Li

Publikováno v: Proceedings of the International Conference on Aerospace System Science and Engineering 2020 ISBN: 9789813360594

As society developed expeditiously, more attentions have been paid towards harm of noise. Thus beamforming technology based on phased microphone array is widely used in rotating acoustic source localization. In this paper, a ring microphone array is

Publikováno v: Prenatal Diagnosis. 37:156-161

OBJECTIVES Outlet ventricular septal defects (VSDs) are usually suspected on the five-chamber view of the fetal heart; however, postnatal confirmation occurs only in a small number of cases. The aim of this study was to evaluate if the systematic ass
