Capabilities

Below are examples of technology areas that describe some of GIRD Systems current and recent projects. Beyond these projects, we are also constantly exploring new lines of research developed through partnerships and the Small Business Innovation Research (SBIR) program.

Interference Mitigation

GIRD Systems has developed novel algorithms to remove sources of interference that are not susceptible to traditional filtering techniques. Our approach offers real-time suppression and mitigation of interference sources even when the characteristics of the inteference source are unknown.

GPS-Denied Location

As systems become increasingly dependent on positioning information, there is a growing need for systems that determine position in environments where GPS availability is denied or suppressed. GIRD Systems has developed a new approach for the DoD that leverages existing communications systems to determine the position of a system user.

Wideband RF Direction Finding

GIRD Systems has developed systems for several wideband RF systems for digital direction finding. Our algorithms allow SIGINT and COMINT systems to find the direction of arrival of signals even when signal characteristics such as the bandwidth, center frequency and polarization are unknown to the operator.

Compressive Sensing

Compressive sensing is an emerging area of research that allows advanced processing techniques to process bandwidths beyond the limits typically encountered due to the sampling rate limitations of the hardware and the Nyquist criterion. GIRD Systems has developed novel techniques to enhance the compressive sensing algorithms found in literature and has demonstrated the viability of these techniques in hardware.

Communications Waveforms

GIRD Systems has worked on projects in communications waveform design and enhancement for military communications systems. Given the constraints of an application, selecting the right waveform characteristics can significantly improve the capabilities and reliability of a communications system.
We also have the ability to port communications waveforms to platforms such as software defined radios. Our efficient implementations minimize resource usage on embedded platforms where limited memory and processing power must be shared among multiple tasks.
