The new generation of radio systems, such as LOFAR, HERA, EISCAT-3D, SKA etc., are changing the way that astronomy, space science and ionospheric physics are done. These new detector systems have also benefited from significantly improved digitisation and digital signal processing, which have enhanced the sensitivity, flexibility and capabilities of the radio frequency instrumentation. However, they have also led to a substantial increase in the data volume and data rates from such systems, which must be compensated for by improved data transport, storage and post-processing systems. Given these improvements, spectrum management has also become increasingly important for mitigating the effects of radio frequency interference (RFI).

 In this discussion meeting we will bring together experts working on radio frequency systems from the astronomical, MIST and engineering sectors, to share developments in their fields that impact the use of modern radio frequency detector systems. This includes front-end design, digital signal processing, RFI excision, ionospheric measurement and calibration, as well as post-processing and computational challenges.
