The Methanol Multibeam Survey [PDF]

Proceedings of the International Astronomical Union, 2012
A purpose built 7-beam methanol receiver, installed on the Parkes Radio Telescope, was used to survey the Galactic plane for newly forming high mass stars, pinpointed by strong methanol maser emission at 6.7 GHz. The Methanol Multibeam (MMB) survey observed over 60% of the Galactic plane, detecting close to 1000 sources.

Seabed sediments (grain size) of Nordland VI, offshore north Norway

Journal of Maps, 2017
This paper presents a seabed sediments (grain size) map of the Nordland VI area (25,000 km2) off the Lofoten islands, north Norway. The map is based on multibeam echosounder data (bathymetry and backscatter), visual analysis of 215 video transects (each ...

Hybrid Machine Learning and CUBE Method for Multibeam Data Cleaning [PDF]

TransNav
Multibeam data contains different types of errors that are classified as systematic errors, random errors and gross errors (outliers). Accurate bathymetric base surface production requires efficient cleaning methods to detect and reject the outliers. The

Australian multibeam guidelines

, 2018
Australia’s Multibeam Guidelines were established by the AusSeabed consortium. The guidelines provide procedures mainly on survey planning, data acquisition and submission i.e. from the pre-survey planning phase to the data submission phase, off the ship. They are designed for a range of audiences, from those experienced in seafloor mapping using swath

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 ...

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 ...
