Abstract
This paper presents an approach for tar- get behavior tendency estimation (Receding, Approach- ing). It is developed on the principles of Dezert- Smarandache theory (DSmT) of plausible and para- doxical reasoning applied to conventional sonar ampli- tude measurements, which serve as an evidence for COT- responding decision-making procedures. In some real world situations it is dificult to finalize these proce- dures, because of discrepancies in measurements inter- pretation. In these cases the decision-making process leads to conflicts, which cannot be resolved using the well-know methods. The aim of the perjomed study is to present and to approve the ability of DSmT to fi- nalize successfully the decision-making process and to assure awareness about the tendencies of target behav- ior in case of discrepancies in measurements interpre- tation. An example is provided to illustrate the bene- fit of the proposed approach application in comparison of fuzzy logic approach, and its ability to improve the overall tracking perfonnance.

In our case we suppose that in parallel with measured local angle the observed target emits constant signal, which is perceived by the sensor with a non-constant, but a varying strength

Summary
Angle-only tracking systems based on sonars are poorly developed topic due to a number of complications. Our goal is, utilizing received amplitude feature measurement, to predict and to estimate the possible (C1) The DST considers a discrete and finite frame of target behavior tendencies. Some subjectivity on the information provided by a source of information is almost unavoidable, otherwise this would assume, as within the DST, that all bodies of evidence have an objective/universal (possibly uncertain) interpretation or measure of the phenomena under consideration which rarely (never) occurs in reality. The DSmT includes the possibility to deal with evidences arising from different sources of information which don’t have access to absolute interpretation of the elements θi under consideration and can be interpreted as a general and direct extension of probability theory and the DST in the following sense.
