TY - GEN N2 - Radar tracking operations are aimed at determining the flight path of a target. They are usually carried out by means of a ?monopulse radar tracker? able to recover the position of the target by the reflected echo of a previously transmitted pulse [1]. Towards this purposes the antenna of the tracker system is required to generate two difference beams on the same aperture: a ?sum? beam and a ?difference? one.
