INTERACTIVE SONAR TARGET CLASSIFICATION DISPLAY SYSTEM USING NONLINEAR FEATURE SELECTION TECHNIQUES

摘要

A prototype man-machine interactive display system for target classification has been designed and implemented. This system features a high degree of interaction between the display operator and the computer in the processing and display of multi-dimensional target classification data. The functions of the system are to demonstrate the feasibility of direct operator interaction with the processing of a data base and to aid in the development and evaluation of target classification strategies. The interactive target-classification system is unique for both its use of nonlinear feature-selection transformations to reduce the dimensionality of the measurement space data and its use of steroscopic techniques for direct viewing of the resulting three-dimensional target-classification feature space. Thus, the interactive target-classification system introduces some new alternatives to traditional sonar data processing and display techniques.
