Scientific paper

A rigorous solution of the problem of the separation of broadband signals which differ in frequency drift velocities was obtained by the Fourier method. The variation in noise during the restoration of the signals is investigated. A novel scheme for the construction of a multichannel receiving system based on the use of difference sets is presented. This system has fewer channels and greater sensitivity, and requires simpler data processing. An example of the detection of a faint signal from a pulsar and intense noise suppression is provided.
