This paper describes efforts in the development of an autonomous structural health monitoring system. This integrated, portable hardware/software system is designed with an intuitive, user-friendly Graphical User Interface so that a technician or astronaut, who does not have extensive experience in damage detection, can perform the structural inspection. The hardware consists of a laptop computer, data acquisition system, and both undamaged and preselected damaged structures. The software includes several operation buttons that allow a more experienced user to select different analyses or graphic options interactively. The system currently employs both Minimum Rank Perturbation Theory and optimal matrix adjustment techniques for the analysis and the damage detection results from both methods can be compared on-line. Several analysis features and graphical displays of the integrated software are presented utilizing damage detection results of a cantilevered structure.
