This paper overviews a few methods of TMA (target motion analysis), such as only bearing TMA, multiple information fusion TMA, bearing-Doppler TMA, distance estimation with bearing and noise energy, matched-field location combined with TMA etc. We herein provide a new idea for the design of TMA functions in fully integrated and distributed submarine combat system.

We enhances the TMA functions from the point of view of submarine combat system, fully applying the information of multi-sensors and the operator´s subjective decisions in automatic and in manual modes. It will serve better in tactical decision making and provide more accurate results of target motion parameters. Compared with the normal design of TMA, this design has developed a function of target manoeuvre recognition, added the manual TMA function, and designed a display on which the operator can easyly observe TMA output, target motion and therefor improving track of targets.
