Border surveillance applications require low false alarm rates and long endurance. These requirements have not changed since unattended ground sensors (UGS) were first used to monitor Viet Cong activity along the Ho Chi Minh Trail in the 1960's. However the targets are quite different today. Then the targets of interest were large military vehicles with strong acoustic, seismic and magnetic signatures. Currently, the requirements imposed by new terrorist threats and illegal border crossings have changed the emphasis to the monitoring of light vehicles and foot traffic. Unlike with military driven requirements cost of ownership and ease of employment are at least as critical as sensor performance.
