The development of refined methods of automated LOFAR-gram reading is an improvement to the PACT techniques of extracting spectral clues from a received signal. It is now intended that the implementation of these techniques be primarily by a general-purpose digital computer. Development of practical methods of predicting computing important spectral characteristics of passive sonar signals from a knowledge of the generating ships targets engineering and operating configuration. More specifically, this problem is approached by developing generic models of certain vibratory ships components. Integral to the task of developing prediction methods are the subtasks of collecting the two types of data required-tape recordings of ship-generated acoustic signals and engineering data on the corresponding ships. Development of a classification algorithm which operates on the spectral clues extracted by the LOFAR-gram reader, obtaining a set of probable ship design characteristics, and thence a set of probable target classifications.
