The U.S. Border Patrol is in critical need of improved surveillance for detection of people and vehicles illegally crossing the Southern Border, particularly in rural areas. AETC will conduct a Phase 1 feasibility study of acoustics-based surveillance and signal processing techniques to address the Southern Border problem. The overall system concept encompasses a network of low-cost acoustic sensors and advanced signal processing for automated detection and classification of border crossings. This study will (1) identify specific signatures for acoustic monitoring of people and vehicles crossing the border, (2) design and implement advanced signal processing algorithms required for automatic detection and classification of these signatures, (3) define sensor configuration and front-end hardware, (4) determine maximum detection range, (5) estimate PD and PFA performance, and (6) assess cost per unit distance of border monitored for this capability. In addressing this Homeland Security problem, AETC will leverage substantial knowledge and expertise in acoustic signal processing derived from relevant experience in U.S. defense applications. As a commercialization strategy, AETC plans to license the technology developed under this SBIR to manufacturers who will produce and sell platforms for border and facility security. Potential end-users would include the U.S. Border Patrol, military, and law enforcement agencies.
