Abstract: The
expressions for structural and antenna components of two-position scattering
field of plane array of dipoles of phase monopulse system are obtained on the
base of scattering matrix technique. The scheme of excitement of array consists
of four forming multiterminal networks with phase shifters in channels of
radiators and the total and differential converter. The matrix of dispersion of
entrances of vibrators is found through their matrix of resistance which is
determined by a method of induced EDS. Estimates of various components of the
effective area of dispersion (EAD) are received on the basis of power approach
(L.I. Ponomarev applied earlier to problems of dispersion). Volume directional
patterns of a scattered field and the maximum values the EAD component for a
array from 144 vibrators are provided in the report.
Key words:
antenna array, phase monopulse system,
directional patterns of a scattered field.
