Background/Objectives: In underwater sonar environment, the target motion parameters can be obtained only when observer maneuvers in some particular manner is satisfying certain requirements.
Methods/Statistical analysis: The algorithm is evaluated using Line of sight measurements which are obtained from intercept radar. Though the recommended maneuver may not be optimum, observability is ensured.
Findings: Recursive Maximum Likelihood Estimator with initial estimation from Recursive Pseudo Linear Estimator is used to evaluate the process.
Application/Improvements: For the purpose of analysis, the proposed observer maneuver is used for a typical scenario at low, medium and high target angles. Convergence time and the accuracy of the solution in Monte-Carlo simulation are presented in detail.
