"Technology for Next Generation Space-Earth Environmental Radio Science", a workshop by ISEE: Top page
Conference Rationale
Low frequency radio observations are used as one of the main research tools in space-earth environmental sciences and astronomy. Low-frequency radio observation devices are able to effectively obtain a large collecting area and a wide field of view by forming an array with many antennas. Indeed, there are such large radio telescopes and radars for space-earth environmental sciences. In radio astronomy, transient science attracts much attention due to the discovery of fast radio bursts, along with developments of new generation receivers such as ASKAP's PAF and Parkes' UWL. The construction of the world's largest low-frequency radio interferometer, SKA, will start in 2021.
Phased arrays and wideband receivers are very common and applicable technologies that benefit various research fields such ans space science, geophysics, astronomy, meteorology, and so on. Meanwhile, such technologies have been developed in each field due to a histrocal background. Moreover, new problems such as radio frequency interference (RFI) and high data rate signal processing emerged along with the improvement of receivers. Therefore, in this conference, we invite experts of developing low-frequency radio istruments across research fields. We aim to provide exchange of the latest development information, clarify common technical elements and problems, and conduct interdisciplinary joint research and collaboration.
The conference will be held remotely. The presentation slides will be uploaded on this website as the conference proceedings.
