Description: | The picture above shows the WHAT (Westerbork High-band Antenna Test facility) field at the WRST site against the background of a 'convential' WSRT telescope. The high-band antennae field on the picture consists of the second generation prototype high-band antennae and their beamformers. The frequency range of this system is 120 MHz to 240 MHz which overlaps for a big part with that of the WSRT LFFE (Low Frequency Front-End) system (115 - 180 MHz). The goal of the WHAT experimental setup at the WSRT site is to test the high-band antennae systems in aspects related to efficiency, noise, stability, layout, beam-forming, in conjunction with the WSRT, which has a well-known performance. To this purpose, observations are being done with the WHAT signal injected into the WSRT backend system. Picture: Harm-Jan Stiepel and Adriaan Renting Text: Arno Schoenmakers and Hans van der Marel |
