Antenna equipment of the Lebedev Institute BSA radio telescope facility
Abstract
The phasing system, beam pattern shaping, trunk amplification system, receiving equipment, and performance of the Lebedev Physics Institute (FIAN) large scanning antenna (BSA) are described. The radio telescope comprises a phased array extending 384 m x 187 m controlled in elevation by remote phase inverters, and operating in the meter wavelength band (102.5 + or - 1.5 MHz). The telescope scans from +90 to -20 deg in declination. Simultaneous reception from 16 directions is facilitated by a Butler phasing matrix. The array is designed for research on pulsars, and is capable of utilizing pulsar flicker to advantage in studies of the interstellar medium or analogous studies of interplanetary plasma by using discrete radio sources.
