Research Topics


This Phase I SBIR proposal will investigate and develop techniques for detecting, identifying, tracing, predicting, and jamming Frequency Hopping (FH) signals. The techniques will be architected and tailored for hosting on an existing Radix Technologies demonstration unit, called Bumble Bee, that performs the detection, tracking, deinterleaving, and copy of FH emitters and requires only a single 19" rack-mounted chassis and a lap-top computer HMI. The Phase II activities will entail the constrcution of a new, upgraded Jamming Bumble Bee (J-BBee) system with the integration of the techniques defined in Phase I and the addition of a signal generator and power amplifier for transmission of the jamming waveform.The Jamming Bumble Bee capitalizes on a number of technical advances that Radix has developed to exploit the emerging spread spectrum communications threat. This effort is uniquely positioned to expand upon an existing electronic support (ES) FH system, quickly demonstrates an electronic attack (EA) capability for FH signals, and it will provide a demonstration and countermeasure application as they are developed.
