Badanie przetwornika o nierównomiernie rozmieszczonych elementach

General object of nonuniform array design is the approximation of desired beam pattern with reduced number of elements which are required for uniform array of d/α=0,5. This work intends to study possibilities of design procedures lead to useful, nonuniform arrays with elements situated in raster d/α=0,5. Options of spacing elements for nonuniform arrays presented beneath are reduced to the raster d/α=0,5, which enable easier technical realisation of the beamformer. Arrays with equal excited elements have been used, what is highly practical, both for transmission and receiving. Many designs of arrays have been proposed and tested The beam patterns for steered beams are presented.
