SOF ES Systems
SOF systems are modular ESM/ELINT systems for use in manned and unmanned airborne,ground, and shipborne monitoring systems. Their primary function is to detect, identify, locate and track RF signals over wide instantaneous bandwidths. System modularity allows installation of multiple IF channels in a common hardware infrastructure. RF signals are collected at the sensor antennas and converted into multiple IF bands. Each IF band on an SOF system handles an instantaneous bandwidth of >1 GHz and can provide all the classical ELINT data, including bearing on every detected signal within its band. The SOF system relies on proven Finder software operating on an embedded Linux-based single board computer. It includes support for a variety of interfaces (1553, A429, serial, GbE, etc.) for tying into existing platform infrastructure (GPS, INS, network). In also includes support for receiving and decoding AIS messages for monitoring shipping traffic.
