Abstract: Situational awareness plays a critical role in the decision-making process for today's Soldier. It is important for a Soldier to know from what direction an enemy is approaching. Obtaining and using information gathered from low-cost sensors like acoustic, seismic, e-field, imagery, accelerometers, and others can provide a means to monitor human-based activity. This report investigates the feasibility of using an array of low-cost sensors for determining the patterns and activities of people that occur in a typical breakroom during lunch time. The test results show that it is possible to detect and interpret activity in urban settings, such as in buildings, with low-cost sensors and, thus, show promise for enhancing the situational awareness of today's Soldier.
