Monopulse radars are often used by the U.S. Navy Department to track airborne targets such as missiles attacking ships. In order to effectively make use of the target position data provided by the radar, an estimate of the radar output accuracy must be known. This report describes portions of research performed at Naval Surface Warfare Center, Dahlgren Division NSWCDD to develop statistical models of monopulse ratio behavior to improve accuracy analysis of the monopulse radar. The products of this work include a formula for the distribution of the real valued part of the radar signal. Also developed were two tools to compare this distribution with a normal distribution. With these formulas, we showed that, given certain assumptions, this distribution can be approximated by a normal distribution. Finally, this work showed the validity of certain pre-existing formulas developed at NSWCDD. These results are useful in developing algorithms for assessing the accuracy of target location estimates by monopulse radars.
