Radio Interferometry Principles . Radio Interferometry Signal Processing . ... A radio interferometer consists of a pair of directional antennas that are tuned to receive radio emissions from a source in a desired RF band. ... The antennas are pointed at the radio source of interest and are set up to receive the signal and process it into a form suitable for transmission to the correlator. ... In connected element interferometry, the digital signal goes directly to the correlator. ...

... Director of the RAS ISR . RAS Academician . ... Astrophysics module Kvant of the orbital complex Mir launched in 1987 contains the largest on the station complex of the scientific equipment named the orbital observatory Roentgen. Observatory Roentgen consists of 4 X-ray telescopes, jointly exceeding the range of energies from 2 to 800 keV. ... Among the most significant results that were received in the observatory Roentgen are: . ... measurement of the periods of 9 X-ray pulsars; . ...

... The set of equipment includes 8-mm band transmitting/receiving module (TRM), 1.5-cm band multi-channel receiver, and 2-cm band receiving module. TRM, operating in 8-mm range, assures two-way communication with up to 10 Mbaud rate (33–36 GHz input/output frequency). The 1.5-cm receiver is designed for receiving the service and scientific data from the space radio interferometer in 18–26 GHz frequency range (8 channels) with up to 36 Mbaud data transfer rate. ... 1.5-cm multi-channel receiver . ...
