The many modern mobile radars used antenna system with mechanical rotation in the azimuthal plane. This antenna system has to have radiation pattern with fixed narrow beam in horizontal plane. For antenna array this radiation pattern can be formed with dividing system used and antenna elements, printed on the common circuit board, without fed lines and connectors between divider and radiators. Scanning in vertical plane for this radar system performed by used linear phase shifts between rows of antenna array. The problem of measure of the amplitude-phase distribution for antenna rows is consider.
This paper describing questions interaction between linear antenna array elements during testing and the probe device at measurement of the amplitude-phase distribution along a of linear array are considered. It is shown that use of the calculation model constructed in a CAD of electrodynamic level allows to choose mutual position of the radiators providing their matching on the basis of results of a numerical experiment. Two methods of measurement of the amplitude-phase distribution along a of linear array are compared. The first method used moving probe device along linear antenna array. In the second method probe device have number radiators, equal number of testing linear array elements. During measure one of probe device radiator connected to measure device with use controlling commutator.
Is show that use probe device with controlling commutator allows to reduce significantly measure time. The selectivity of the various types probe device with different mutual positions is estimated. Comparison results of numerical modeling and measurements is given.
