Real-Time RFI Mitigation in SPOTLIGHT: A Two-Stage Approach for Transient Searches
Raghav Wani, Jayanta Roy, Harshavardhan Reddy +10
Radio Frequency Interference (RFI) remains one of the primary challenges limiting the sensitivity and reliability of modern radio transient surveys, particularly for real-time sear…
Real-time RFI Mitigation Techniques in Radio Astronomy and Their Practical Limitations
Kaushal D. Buch, Thushara Gunaratne, Gregory Hellbourg +2
Radio astronomy is facing critical challenges due to an ever-increasing human-made signal density filling up the radio spectrum. With the rise of satellites, mobile networks, and o…
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…
Real-time RFI Excision Techniques and their Limitations
Kaushal D. Buch, Ruta Kale, Kishor D. Naik +8
Contemporary real-time RFI mitigation is carried out at different stages primarily using regulatory and technical approaches. Regulatory approaches include spectrum management, rad…
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 Expanded Giant Metrewave Radio Telescope
N. N. Patra, N. Kanekar, J. N. Chengalur +22
With 30 antennas and a maximum baseline length of 25 km, the Giant Metrewave Radio Telescope (GMRT) is the premier low-frequency radio interferometer today. We have carried out a s…
Implementing and Characterizing Real-time Broadband RFI Excision for the GMRT Wideband Backend
Kaushal D. Buch, Kishor Naik, Swapnil Nalawade +3
The Giant Metrewave Radio Telescope (GMRT) is being upgraded to increase the receiver sensitivity. This makes the receiver more susceptible to man-made Radio Frequency Interference…
A Decade of Developing Radio-Astronomy Instrumentation using CASPER Open-Source Technology
Jack Hickish, Zuhra Abdurashidova, Zaki Ali +33
The Collaboration for Astronomy Signal Processing and Electronics Research (CASPER) has been working for a decade to reduce the time and cost of designing, building and deploying n…
