Monopulse Compromise Arrays: A Review

A monopulse RADAR is a device aimed to detect the position of a target by using the information collected from an antenna that generates two different kinds of beams on the same aperture, namely sum and difference pattern. These beams can be obtained by means of reflector antenna with two or three feeds, or by using linear (2D tracking) or planar (3D tracking) arrays. The latter solution is usually preferred since antenna arrays are easier to build and the beam patterns can be steered electronically. Moreover, such a structure can be installed on mobile vehicles.
