ABSTRACT:
A method for scanning of antenna array, wherein on output signals from radiating elements are applied phases offset in order to obtain signals with approximately equal phases. The obtained signals are subsequently summated. The method is characterized in that before application of phase control the output signals from radiating elements are grouped by means of summation of the signals with approximately equal phases in order to form equivalent group signal. Subsequently the phase offset is applied on all group signals and subsequently all group signals are summated. A phase control device for the application of the method comprises, phase shifting elements grouped in a phase control block, a controlling block, and a block of switches connected between inputs from the antenna radiating elements and the phase control block, wherein the outputs of the controlling block are connected to control inputs of the block of switches, and the phase control block includes internal summators (3) whose inputs are connected to the block of switches (2) and outputs are connected to a common summation circuit (4) via corresponding phase shifting element (5).
