Abstract :
The problem of amplitude-phase synthesis of waveguide array in three statements is considered. The amplitude radiation pattern, the power radiation pattern, as well as the characteristic describing efficiency of the array radiation are proposed as radiating characteristics of array. The synthesis problems are formulated as the variational ones. The appropriate nonlinear equations are received. Efficiency of synthesis for various types of the prescribed amplitude and power radiation patterns is numerically investigated.
