URSI Extended Abstract Template

Radio Telescopes are inevitably exposed to undesirable radio frequency interference (RFI) signals from terrestrial human activity and are becoming stronger with time and with increasing population density, urbanisation and modernisation of communication system degrading the quality of astronomical observations. The problem is aggravated with highly sensitive radio telescope at low frequency and further gets affected with broadband radio astronomy receivers.An additional threat comes from self-generated RFI produced by the increasingly computer controlled and data intensive operations of a typical radio telescope. All these aspects of RFI significantly affect the highly sensitive upgraded Giant Metrewave Radio Telescope (uGMRT), working at low frequency with a seamless frequency coverage from 50MHz to 1.5GHz having an instantaneous bandwidth of 400MHz.
