Progression of Digital-Receiver Architecture: From MWA to SKA1-Low,and beyond
Girish B. S., Harshavardhan Reddy S., Shiv Sethi +14
Backed by advances in digital electronics, signal processing, computation, and storage technologies, aperture arrays, which had strongly influenced the design of telescopes in the…
Antennas for low-frequency radio telescope of SKA
Agaram Raghunathan, Keerthipriya Satish, Arasi Sathyamurthy +4
The low-frequency radio telescope of the Square Kilometre Array (SKA) is being built by the international radio astronomical community to (i) have orders of magnitude higher sensit…
A Floating Octave Bandwidth Cone-Disc Antenna for Detection of Cosmic Dawn
Agaram Raghunathan, Ravi Subrahmanyan, N. Udaya Shankar +9
The critical component of radio astronomy radiometers built to detect redshifted 21-cm signals from Cosmic Dawn is the antenna element. We describe the design and performance of an…
SARAS 3 CD/EoR Radiometer: Design and Performance of the Receiver
Jishnu Nambissan T., Ravi Subrahmanyan, R. Somashekar +6
SARAS is an ongoing experiment aiming to detect the redshifted global 21-cm signal expected from Cosmic Dawn (CD) and the Epoch of Reionization (EoR). Standard cosmological models…
SARAS CD/EoR Radiometer: Design and performance of the Digital Correlation Spectrometer
B. S. Girish, K. S. Srivani, Ravi Subrahmanyan +6
In the currently accepted model for cosmic baryon evolution, Cosmic Dawn and the Epoch of Reionization are significant times when first light from the first luminous objects emerge…
The Receiver System for the Ooty Wide Field Array
C. R. Subrahmanya, P. Prasad, B. S. Girish +3
The legacy Ooty Radio Telescope (ORT) is being reconfigured as a 264-element synthesis telescope, called the Ooty Wide Field Array (OWFA). Its antenna elements are the contiguous 1…
