Abstract:

The Maximum Likelihood Probabilistic Data Association ML-PDA tracker and the Maximum Likelihood Probabilistic Multi-Hypothesis ML-PMHT tracker were applied to five synthetic multistatic active sonar scenarios featuring multiple targets, multiple sources, and multiple receivers. For each of the scenarios, Monte Carlo testing was performed to quantify the performance differences between the two algorithms. Both trackers ended up performing well. For most scenarios, MLPMHT slightly outperformed ML-PDA in terms of in-track percentage. However, in a scenario with closely-spaced targets, ML-PDA exhibited superior performance.
