Measuring Target Position with the Fucas Phased-Array Radar System

摘要

An experimental system with the ability to measure the position of targets within the main radar antenna beam by applying monopulse processing to the echoes of a single transmission is presented. The position estimation process is described and the results of an experiment to determine its performance are presented. The experiment was done with an almost stationary helicopter, so that the effects of strong target glint had to be considered. The influence of the application of incoherent echo integration, frequency agility and moving target indication are examined. A single target echo from within the half power beam contour is sufficient to provide an accurate position estimate within 4% rms error. The applications of frequency agility reduces the effect of target glint. The monopulse performance can be improved by using a set of monopulse relations.
