Introduction to multiradar tracking systems

Multiradar tracking (MRT) using distributed and centralized systems is discussed. Although MRT has advantages with respect to a monoradar system (e.g., a target may be tracked, with greater accuracy, over an area wider than the coverage of each radar) difficulties arise in organization and processing of measurement data. Unlike the monoradar case, the data organization according to azimuthal sectorization is not possible, because the measurements come from various spatial sectors in a nonuniform manner. In the overlapped area, the targets are detected by different radars which are asynchronously scanning and have different scan periods and accuracies.
