Estimation of target angular data by monopulse radar with off-axis direction finding

A possibility of monopulse method of direction-finding applied to estimate the target angular data in track-while-scan mode is considered. With the purpose of guaranteed measurements inside the working area, the informative signs that define the conditions of hitting the target angular data into the working area are used. The base of two signs formation is the property of boresight curve odd symmetry and the property of this curve constant slope within the working area. An efficiency analysis for the target direction-finding method with the use of informative signs is realized by statistical computer simulation. The probabilistic assessments of true sign formation inside and outside the working area are derived.
