Findings from a Combined Subsea LiDAR and Multibeam Survey at Kingston Reef, Western Australia
Remote Sensing, 2020 Light Detection and Ranging (LiDAR), a comparatively new technology in the field of underwater surveying, has principally been used for taking precise measurement of undersea structures in the oil and gas industry.

Multibeam Antenna for -Band CubeSat Connectivity Using 3-D Printed Lens and Antenna Array
IEEE Antennas and Wireless Propagation Letters, 2022 In this letter, the design of a passive multibeam lens antenna is proposed for the CubeSat space communication system as an alternative application of a 2-D microstrip antenna array that has originally been designed for a 39-GHz 5G multi-user, multiple ...

The precision calibration of depth and resolution for multibeam sonar in anechoic pool in the laboratory [PDF]
MATEC Web of Conferences, 2019 The multibeam sonar is an important device for underwater survey, of which the measurement precision is a key parameter. We had designed an equipment to calibrate the depth and resolution precision for multibeam sonar in the anechoic pool in the ...

Robust Design for NOMA-Based Multibeam LEO Satellite Internet of Things [PDF]
IEEE Internet of Things Journal, 2020 In this article, we investigate the issue of massive access in a beyond fifth-generation (B5G) multibeam low-Earth orbit (LEO) satellite Internet-of-Things (IoT) network in the presence of channel phase uncertainty due to channel-state information (CSI ...

Advanced Electronic Materials, EarlyView.A compact passive engineered surface converts changes in microwave frequency into many distinct illumination patterns, allowing nearby objects to be imaged without mechanical scanning, active tuning, or a large antenna array. Operating from 18 to 28 GHz, the single‐port system uses measured field patterns to reconstruct metallic targets and distinguish
