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. %Z This version is a pre-print of the final version available at IEEE.
