| contents | 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 observations in all the bands of the uGMRT during the monsoon of 2018 and 2019. Broadband power-line RFI is almost always present in uGMRT bands 2 (120 - 240 MHz), 3 (300 - 500 MHz) and 4 (550 - 850 MHz), but the monsoon period is chosen to understand the performance in the worst RFI situations arising due to an increase in the wind-speed and moisture. |
