Abstract

This paper is to address a 3-dimensional affordable phased array antenna for multibeam surveillance and tracking radar to support a Fire Control System. This 2m x 2m x 2m phased array antenna system is implemented at S-band and equipped with multi-beam forming capability for 3D electronic scanning without mechanical motors. A beamformer based on two stage Butler matrix for azimuth and elevation control is implemented and integrated to 16 x 16 cross dipole array antenna. Furthermore, to emulate the gun turret functions, we also prepared a mini launcher model for testing purposes to determine the effectiveness of the Fire Control System to acquire, track and lock the target.
