Analysis of the Accuracy of a Proposed Target Motion Analysis Procedure

Abstract

This thesis investigates the accuracy of a recently proposed passive bearings-only Target Motion Analysis (TMA) procedure. The primary method of analysis is to compare computer generated positions of a Target that is moving with a constant course and speed, with the procedurally derived estimated positions. A computer model was developed which simulated several possible interactions between the Target and Own Ship. Estimated parameters of the Target track were computed using the procedure under analysis. These values were compared to the true values generated by the simulation. An analysis of the TMA procedure as originally proposed showed that it failed to accurately estimated the target track parameters. However with some modifications, the accuracy improved significantly and it is felt that the procedure can accurately estimate target range (but not necessarily course and speed) for some target geometries. Keywords: Target detection; Target position indicators; Thesis.
