报告人:Adrian Murphy
报告主题简介:
The Institute for Atmospheric Physics (IAP) of the University of Rostock, Germany, had operated a conventional VHF MST radar adjacent the rocket launch site on the North-Norwegian island Andøya since the late-1990s.  This was a 36 kW, 6 receiver channel radar with a square antenna array comprising 144 Yagis and operating at a frequency of 53.500 MHz.  In addition to routine observations of the troposphere and lower stratosphere, primary purposes of the radar were to (1) study the structure and occurrence of PMSE echoes and (2) provide wind observations to the rocket launch centre to assist in making decisions on the timing of launches to optimise results.
In 2008 a decision was taken to replace the ageing conventional radar with a far more capable system.  After extensive consultation and detailed design studies, it was determined that the replacement system should be a quasi-circular, 433-antenna transceiver system with a power of the order of 800 kW and operating at the same frequency as the original radar.  Siteworks for the transceiver system began in 2009 and installation of the radar hardware was completed in 2011.
Upgrades and enhancements to the original radar hardware and control software continue to the present day.
This presentation will describe the features and capabilities of MAARSY and some of the technical challenges faced during the design of the transceiver system.  Diagrams and images of the hardware and antenna array will be presented and some results will be shown.
