| description | In this paper, a new method of spatial separation of several signals with
different curvatures of the wave front is proposed. The method is based on
the formation of a particular interference field structure of each signal in
the location of the receiving antennas by means of a transmitting phased
sparse linear array antenna. The peculiarity of the interference
electromagnetic field consists in periodically repeating areas in which the
amplitude of the useful signal is many times greater than the amplitudes of
the other transmitted signals, which are electromagnetic interference. In
addition, the electromagnetic interference signal in this area consists of
practically two antiphase components. If in this area a reflective passive
phased antenna array is placed, which will focus the useful signal while
reflecting, it will be increased, and the interference signal will be
significantly weakened. This method of signal separation allows simultaneous
transmission of several signals in the same frequency band, in one direction
and on one polarization, which increases the information transmission speed
in communication systems. |
