Nowadays there are more and more targets, so it is more difficult for radar networking to track the important targets. To
reduce the pressure on radar networking and the waste of ammunition, it is very necessary for radar networking to
recognize the targets. Two target recognition approaches of radar networking based on fuzzy mathematics are proposed
in this paper, which are multi-level fuzzy synthetical evaluation technique and lattice approaching degree technique. By
analyzing the principles, the application techniques are given, the merits and shortcomings are also analyzed, and
applying environments are advised. Another emphasis is the compare between the multiple mono-level fuzzy synthetical
evaluation and the multi-level fuzzy synthetical evaluation, an instance is carried out to illuminate the problem, then the
results are analyzed in theory, the conclusions are gotten which can be instructions for application in engineering.
