BURSTT: Bustling Universe Radio Survey Telescope in Taiwan [PDF]

Publications of the Astronomical Society of the Pacific, 2022
Fast Radio Bursts (FRBs) are bright millisecond-duration radio transients that appear about 1000 times per day, all-sky, for a fluence threshold 5 Jy ms at 600 MHz.

A Software for RFI Analysis of Radio Environment around Radio Telescope

Universe, 2023
Radio astronomy uses radio telescopes to detect very faint emissions from celestial objects. However, human-made radio frequency interference (RFI) is currently a common problem faced by most terrestrial radio telescopes, and it is getting worse with the

Experimental Verification of the Concept of Using LOFAR Radio-Telescopes as Receivers in Passive Radiolocation Systems

Sensors, 2021
The paper presents a new idea of using a low-frequency radio-telescope belonging to the LOFAR network as a receiver in a passive radar system. The structure of a LOFAR radio-telescope station is described in the context of applying this radio-telescope ...

Dynamic Response and Optimal Design of Radio Telescope Structure under Wind Load Excitation

Buildings, 2023
The dynamic response of a radio telescope structure under wind load excitation significantly impacts the accuracy of signal reception. To address this issue, this study established a parametric finite element model of a radio telescope to simulate its ...
