The nonlinear synthesis problem of a plane equidistant antenna array according to the given requirements to an amplitude directivity pattern is considered. When finding the branching lines of solutions of nonlinear integral equations obtained as a result of solution of the synthesis problem, the two-parameter eigenvalue problems with spectral parameters… (More)
The problem of construction of numerical bilateral approximation for determination of branching points of one nonlinear integral operator, arising in the theory of antennas synthesis according to the given amplitude directivity pattern, is considered. The basic difficulty consists in that the kernel of integral operator nonlinearly depends on the parameter,… (More)
