Maximum Likelihood Estimation Applied to Target Motion Analysis Using Second Order Derivatives,
Abstract
The tracking problem of unknown marine platforms using passive sonar measurements is generally referred to as Target Motion Analysis (TMA). This report describes the application of a Maximum Likelihood Estimation (MLE) method to obtain position and velocity estimates of a platform when bearing angle and frequency measurements are available from a passive sonar system. The frequency measurements are related to one or more cardinal frequency peaks from the radiated frequency spectrum by the platform. The MLE method offers the opportunity to use a multi-leg model, i.e. the platform to be localized is assumed to move according to a piecewise linear track, where each part is referred to as a leg. On each leg constant course and speed is assumed. Additionally, bearing and frequency measurements related to bottom reflections of the acoustical signals can be used.
