EISCAT_3D project visited the Cavendish Laboratory of Cambridge University, UK, for discussions with one of the key groups involved in the design of the Square Kilometre Array (SKA). The two projects have a large number of common issues, since the SKA will contain an aperture array covering the frequency range from 70 to 450 MHz, due to be deployed in Western Australia. This frequency range includes the EISCAT_3D band, and the EISCAT_3D team were therefore interested to see the developments in antenna and signal processing technology, with which the Cambridge team were working. The two projects established a good working relationship and identified a number of issues where future collaboration would be desirable.
The picture shows some of the meeting participants at the Lord’s Bridge field site of Cambridge University, where a small test array of “Christmas Tree” log-periodic antennas has been built as a test for the SKA Aperture Array.
