Real-time Broadband RFI Excision for the Upgraded GMRT
Ruta Kale, Kaushal D. Buch, Sanjay Kudale +2
A real-time broadband RFI mitigation system has been developed for the Upgraded GMRT (uGMRT). Here, we report the engineering, imaging, and beam/pulsar results from the test observ…
A detailed study of the polarisation convention of the Giant Metrewave Radio Telescope
Poonam Chandra, S. Suresh Kumar, Sanjay Kudale +5
Our work aims to investigate the polarisation convention of the Giant Metrewave Radio Telescope (GMRT) radio telescope and understand whether the telescope follows the standard IAU…
Real-time RFI Filtering for uGMRT: Overview of the Released System and Relevance to the SKA
Kaushal D. Buch, Ruta Kale, Mekhala Muley +2
Radio Frequency Interference (RFI) of impulsive nature is created by sources like sparking on high-power transmission lines due to gap or corona discharge and automobile sparking,…
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…
Performance Analysis Techniques for Real-time Broadband RFI Filtering System of uGMRT
Kaushal D. Buch, Ruta Kale, Kishor D. Naik +4
Electromagnetic radiation from human activities, known as man-made Radio Frequency Interference (RFI), adversely affects radio astronomy observations. In the vicinity of the Upgrad…
The Polarization Convention of the uGMRT in Band 4
Barnali Das, Sanjay Kudale, Poonam Chandra +3
We present an experiment performed to understand the polarization convention adopted for band 4 (550--900 MHz) of the upgraded Giant Metrewave Radio Telescope (uGMRT). For that we…
A real-time software backend for the GMRT
Jayanta Roy, Yashwant Gupta, Ue-Li Pen +3
The new era of software signal processing has a large impact on radio astronomy instrumentation. Our design and implementation of a 32 antennae, 33 MHz, dual polarization, fully re…
