Abstract (en)
[origin: EP0056984A1] 1. Phase-controlled aerial array with a plurality of individual radiator elements or lines of radiator elements each with a respective phase shifter (PS), which are connected through a common distributor network with a common feed line (Sp), wherein the target distribution of the relative amplitudes of the individual radiator elements (1 to 6) is determined by the location (X1 to X6 ) of the individual radiator element within the radiator array and by the desired aerial polar diagram, characterised thereby, that a readstore for the individual setting of the controllable phase shifters has setting values stored therein, which are so dimensioned in accordance with the deviation of the measured course of the actual relative amplitudes of the individual radiator elements (1 to 6) from the target distribution that the setting value phi n-B for the control of the phases of the n**th radiator element is connected by the relationship see diagramm : EP0056984,P4,F1 with the measured amplitude distribution PA (x) in the aerial aperture in dependence on the co-ordinates x extending parallely to the polar diagram section being considered and the desired polar diagram shape PF (delta) in dependence on the angle of the beam direction delta, wherein delta (x) is so defined that see diagramm : EP0056984,P4,F3 and wherein xn is the co-ordinate of the n**th aerial element, D is the diameter of the aerial aperture, -delta 0 is the angle, at which the radiation shall start, and lambda 0 is the operating wave length and the phase displacement phi const is as desired, but equal for all radiator elements.
