Abstract
In a surveillance radar, a process is disclosed which can determine the angular positions of multiple jammers with the use of a monopulse agile beam antenna. It involves collecting and processing jammer data received via a monopulse antenna, in order to determine jammer location, and to resolve two jammers within the main beam when present. A feature is the use of the ratio of the imaginary and real parts of the difference/sum ratio as a discriminant to select a subset of multiple measurement data points, from which the individual jammer angular locations can be determined, when two jammers are present, by averaging upper and lower percentiles of the real difference/sum ratio data points of that subset.
