Abstract


Context. A particular advantage of uniform circular arrays is the possibility of scanning the beam within 360° in azimuth without
distorting the characteristics of the directivity pattern only by changing the amplitude-phase distribution of the current on its elements.
This feature, combined with modern beamforming techniques and digital methods of beamforming opens the prospect of using
circular arrays in surveillance radars for military and civil purposes instead of antenna systems with mechanical rotation.
Objective. Investigation of the possibility of reducing the sidelobe level of a uniform circular transmit-receive array using known amplitude distributions used for linear arrays.
Methods. For the study, a phase-mode excitation technique is used in which an arbitrary excitation function of a uniform circular array is represented as a sum of phase excitation components (modes), and the circular array antenna pattern is a superposition of patterns produced by individual phase excitation modes. This technique makes it possible to apply for circular arrays the methods used to pattern synthesis and reduce the side lobe level in linear arrays due to the use of a special transformation matrix.
Results. An imitation mathematical model of a discrete uniform circular array has been developed that provides an opportunity to study the efficiency of using amplitude distributions, known for linear arrays, to reduce its side lobe level.
Conclusions. The computational experiments have confirmed the possibility of using the phase-mode excitation technique for a pattern synthesis with low sidelobe level in the uniform circular transmits-receive array. A variant of the practical application of the Dolph-Chebyshev amplitude distribution for the synthesis of a circular array pattern is shown.
