Abstract

Objectives: This paper proposes the own ship manoeuvring strategy to estimate the proper target state in the bearings only tracking. Methods/Statistical Analysis: The modified gain bearings-only extended Kalman filter is used for analysis, where the gain is modifiable. In the context of Target Motion Analysis, the target state is monitored through nonlinear estimations. The own ship exact manoeuvre is to increase the range observability. Findings: The proposed target estimation algorithm is effective in maritime tracking based sonar applications. Application/Improvements: The methodology proposed here is very useful for tracking underwater targets and finds immense usage for Indian Navy.
