Title (EN) RADAR SYSTEM
(FR) SYSTEME RADAR
Abstract: front page image
(EN)A radar system comprises an antenna (2), which consists of a reflector (5) with two vertically mounted receiving elements (6, 7), and two receiving channels (3, 4) connected to the receiving elements. The receiving elements form, in cooperation with the reflector, practically coinciding cosecant-squared beam patterns. A measuring circuit (25), connected to the two receiving channels, measures the phase difference between the signals received in the receiving elements, which phase difference corresponds with the elevation angle of the target from which the signals were received.
(FR)Un systeme radar comprend une antenne (2), qui consiste en un reflecteur (5) avec deux elements recepteurs montes verticalement (6, 7) et deux canaux recepteurs (3, 4) connectes aux elements recepteurs. Les elements recepteurs forment, en association avec le reflecteur, des reseaux a faisceaux compenses pratiquement coincidents. Un circuit de mesure (25), connecte aux deux canaux de reception, mesure la difference de phase entre les signaux recus dans les elements recepteurs, cette difference de phase correspondant a l"angle d"elevation de la cible a partir de laquelle les signaux sont recus.
