New Fourier spectrum analyzer for radio astronomy research at
the RATAN-600
A new digital Fourier spectrograph with the analysis bandwidth of 60 MHz
and 2048 spectral channels was put into operation at the RATAN-600.
Getting information about the studied signal in the time-frequency-power
measurements allows recording and analyzing the signals, rapidly varying
in time. The use of this device facilitates the separation of radio
astronomical signals from noise - the registration of a broadband signal,
divided into a large number of narrow areas provides the capability to
eliminate the distortions, introduced by the interferences stable in
frequency. The presence of information about the moment of registration
in the recorded signal allows to exclude the short-term broadband
spark-type interferences.
