Optimization of Difference Pattern Features in Sub-Arrayed Monopulse Antennas Through and Excitations Matching Procedure

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.
