Abstract: Target motion analysis(TMA) is an important problem for sonar.In order to extract target states more effectively,choosing appropriately measurement set is the first thing.The development of powerful estimation algorithms is another crucial step in solving the TMA problem.This paper provides a concise and a up-to-date survey about the implementation methods of TMA problem for sonar.The TMA methods are loosely grouped into two categories.One is a part of the classical target tracking methods,which takes the data association as the inseparable part of the whole estimation process.The other estimates target state without explicit use of a data association algorithm.
