    GIRD has developed a novel algorithm for detecting the DOA of sources of unknown bandwidths and unknown center frequencies, which provides a wideband extension to well-known MUSIC algorithm and exploits some general signal characteristics to find the DOA of signal sources. A demonstration prototype has been built as part of the requirement of this Air Force SBIR Phase II Project.

    GIRD Systems has developed an interference cancellation prototype for US Navy SPAWAR that usesa novel software-based algorithm to eliminate the effects of narrow in-band interference for DAMA SATCOM receivers. Our interference cancellation techniques can remove multiple narrowband interferers so that the signal of interest can be correctly demodulated.

    GIRD Systems has developed proprietary algorithms to exploit signals of opportunity for geolocation and navigation when access to GPS is jammed or unavailable. An SBIR Phase II program has been completed and a prototype system has been built to demonstrate this capability. Using signals of opportunity, our system is able to detemine its absolute position using a few measurements.

    Compressive sensing allows wide bandwidth processing beyond the limitations normally associated with device sampling rate limitations. GIRD Systems has built and demonstrated our compressive sensing techniques in GPU hardware for multiple projects. Applications for compressive sensing include SIGINT and COMINT systems as well as wide-bandwidth RADAR systems.

    As new communications standards and protocols are adopted, realizing the improvements in the field requires porting the waveforms to new and existing platforms. GIRD Systems has experience working with a wide variety of communications platforms and can port waveforms to nearly any platform with sufficient processing resources.
