Bearings-Only Tracking: Observer Maneuver Recommendation

Abstract

In the maritime environment, object motion analysis using bearings-only measurements in a two-dimensional plane is carried out. The observer usually performs S-maneuver on the line of sight for range observability. This traditional S-maneuver is not preferable always. So, in this research work, a procedure is tried out to understand the scenario online and recommend the maneuver accordingly. Object motion parameters are estimated based on one selected acceptance criteria. Online observer maneuver recommendations are carried out to obtain the solution fast. The algorithm is realized using Monte-Carlo simulation and evaluated against number of scenarios.
