As a company with capabilities in signal processing and active noise control, Signal Systems Corporation (SSC) specializes in distributed acoustic sensors for surveillance and reconnaissance, including applications for ground, in the air, and underwater. Core competencies include: acoustic sensor and sensor array design and optimization accompanied by signal processing that enables source localization, target characterization and tracking with electronic cancellation of platform noise; R&D in advanced sensors and the supporting algorithms/software; prototype production, field testing, and sensor/platform optimization to meet operational requirements. Signal Systems Corporation has expertise in the field of ground vehicle acoustic sensor systems and specializes in platform noise reduction technology. Ongoing research and development efforts in platform noise reduction, acoustics, sensors and signal processing makes SSC uniquely qualified to develop the acoustic sensor system installed on FCS ground vehicles. The firm continues to develop fully automated acoustic sensor systems that incorporate noise cancellation technology, and provide detection, localization and classification of acoustic targets (vehicles & impulsive events).
