SBIR-STTR Award

A notional concept for an Advanced Sigint System is proposed. Features of the concept include use of COTS hardware for most componentry, and use of highly innovative Sonetech algorithms for ESM/ECM resource management, signal classification, Direction Finding, and jammer/ECM control. A novel technique for emitter location in the "urban canyon" environment is proposed in the basic effort; its counterpart in active jamming would allow selective jamming of the emitter while minimizing"electronic fratricide". Study of the active counterpart is proposed as a study option (p.12, para(3)). An overall design implementation will be selected which will maximize flexibility, modularity, and cost-effectiveness of the baseline systems, with growth potential to allow the optional capability to be added later.

The design, assembly and test of an Multi Platform Advanced Sigint System is proposed. Using the out of the phase one effort a mostly cots hardware approach is proposed. The innovations are in the form of software and algorithms. Sonetech's highly innovative algorithms will be used in resource management, Direction Finding and Signal Classification. Sonetech will build, document and test one EDM system. Ground based testing will occur during the prime contract while airborne testing will occur during the Option. Signal classification, Logistics and training are proposed as an option.

Benefits:
Small DF Systems that are easily calibrated and installed on both airborne and ground based platforms would be beneficial to law enforcement in many applications, such as; cellular 911, cellular phone fraud detection, counter drug enforcement, prevention/detection of control tower spoofing. Secondly, the beam forming and nulling techniques demonstrated during this effort could be used at cellular base stations to make efficient use of the limited bandwidths that are available.
