SABRE - A U.K.-German auroral radar
Abstract
Operational characteristics and stare area of the SABRE (Scandinavian and British Radar Experiment) are described. The two SABRE installations are located in Scotland and Sweden and sweep a common area of 23,000 sq km. Each unit broadcasts a 50 kW pulse, with the Scottish set using 153.2 MHz and the Swedish antenna broadcasting at 142.585 MHz. Both are pulsed bistatic systems using broad beam transmitters and a multiple narrow beam phased array receiving antenna. The radars are capable of measuring the plasma drift velocity in the auroral zone ionosphere at 110 km altitude. The installations are computer controlled and configured for unmanned operation. A range of resolution, with sampling every 100 microsec, is 15 km, with data available for both range intensity and Doppler format.
