Space errors distribution and registration algorithm simulation of the multi-radar network system

Space registration is the pivotal part in the multi-targets tracking system. According to the real multi-radar network, the space errors are classified, and the distribution of sources which creating measurement errors are analyzed in detail. Furthermore, some registration algorithms are lucubrated, and the equation of target flight path transforming based on Earth Coordinate of Earth Center is deduced, the general least square algorithm based on LS is also done, simulation results show its efficiency. When system errors are not relative sufficiently small, the algorithm will become invalid. So reducing the errors of system original adjustment is very important.
