Abstract:

A theoretical analysis of the performance of a nearest-prototype classifier nearest in the sense of Euclidean distance is presented as an approximate analysis of the performance of the Terrain Contour Matching Navigation System TERCOM. The analysis is used to predict classifier performance on both artificially generated terrain with Gauss-Markov statistics and on real-world terrain. Over 150 simulation runs were performed over such terrain having added Gauss-Markov noise independent of the terrain process with 6 different noise levels. Results of the simulation are presented, giving performance as a function of signalnoise ratio and as a function of terrain roughness. Measured miss-distances are also presented. The simulation also includes the performance of a nearest-prototype classifier based on mean absolute distance the first Minkowski metric, which is the actual metric employed in TERCOM.
