An Analysis of Digital Signal Processing in Monopulse Radars

Abstract: The most effective method for deriving information about spatial angles of a target is using Monopulse Radars. The name derives from the fact that the method is theoretically capable of obtaining a target`s angles using only one (mono) pulse. The Monopulse Radar System is mainly used for target detection and tracking. The information on the target angular position is determined by comparison of signals received in two or more simultaneous beams. A target will be seen by radar from the moment it enters the main antenna beam or from the moment it is illuminated by the transmitted radar antenna beam. The signal processor is that part of the system that separates the target from clutter on the basis of Doppler content and amplitude characteristics.

Keywords: Spatial Angles, Bore sight Axis, Clutter and Doppler content.
