Development of an EM-Based Lifeform Detector

Abstract

Georgia Tech is currently conducting a successful program to develop an electromagnetically-based lifeform detector capable of detecting vital signs- related information in battlefield casualties from extremely long ranges (10-100 meters). The original program goal was to develop a capability to detect respiratory activity in battlefield casualties from ranges up to 30 meters. However, because of the success of early program efforts, and the Navy's wishes to also detect cardiac activity, the program scope was expanded to include detection of respiratory and cardiac activity and the desired detection range was extended to 100 meters. The lifeform detector (LFD) being developed on this program measures and analyzes scattered electromagnetic fields to detect respiratory and cardiac motions associated with the casualty being evaluated. Because antenna-based techniques are being used to perform the required scattered-field measurements, true remote-sensing is achieved. That is, a casualty being evaluated does not have to be wearing or carrying a biomedical transducer or other type of auxillary device. This fact greatly enhances the attractiveness and potential usefulness of the LFD.
