Pulsar Backend for 21 CentiMeter Array: Implementation of Data Acquisition and Initial Results
Yukai Zhou, Junhua Gu, Mengyao Xue +8
We implemented a data acquisition system for 21 CentiMeter Array (21CMA), enabling baseband observations targeting pulsars and fast radio bursts. Based on the Radio Frequency Syste…
The Next-Generation 21CMA Telescope: Design, Commissioning, and Instrumental Effects in an SKA-LFAA-Like System
Jun-Hua Gu, Quan Guo, Liang Dong +11
As the Square Kilometre Array (SKA) approaches operational status, its complex digital architecture introduces new instrumental challenges. To explore relevant observational and da…
An Attempt to Search for Unintended Electromagnetic Radiation from Starlink Satellites with the 21 Centimeter Array: Methodology and RFI Characterization
Xupiao Yang, Qijun Zhi, Yanbin Yang +6
The rapid expansion of low-Earth-orbit (LEO) megaconstellations introduces new risks to radio astronomy from unintended electromagnetic radiation (UEMR). In this work, we present a…
Simulation and Data Processing of Beamforming Experiments with Four 21CMA Stations
Feiyu Zhao, Quan Guo, Junhua Gu +3
We present an end-to-end simulation and data-processing framework for digital beamforming experiments conducted with four stations of the 21 Centimeter Array (21CMA). Motivated by…
