Abstract

The multiple object tracking radar was put in operation in November, 1999. As one of the important radar subsystems, the phased array antenna system displayed good tactical properties and featured a high antenna gain and low cross-polarization (antenna efficiency /spl ges/31%, circular polarization axial ratio <1 dB). Its one-degree pencil beam can be positioned with high accuracy to any point within the array´s cone scan coverage. Some important antenna parameters are listed.
