Monopulse radar
A monopulse radar is a radar system that compares the received signal from a single
radar pulse against itself with an aim of comparing the signal as seen in multiple
polarizations or directions. The most common form of monopulse radar is the
adaptation of conical scanning radar which compares the return from two directions to
directly measure the location of the target. It is important to note that most of the
radars that were designed since the 1960s are monopulse radars.
