Computer Circuit Board Macro


GSTA's team has worked on frequency ranges as low as the ultralow frequency (ULF) bands below 60 Hz up to X-band microwave regoins. The work has included experimental work on RFID systems, power line monitoring, directional coupler sensors, weak signal detection, dynamic radar cross sections, antennas and RF circuits. Computationally, we have worked on synthetic aperture radar models, finite element modeling of near field problems, and magnetic induction.

Signal Processing

Two very common problems with which we are asked to help include signal detection and signal classification. For signal detection, we have employed methods such as constant false alarm rate (CFAR) detectors, computed receiver operating characteristics (ROC) on VLF EM, RFID sensors, and microwave problems. In signal classification, we have used and extended  joint-time frequency analysis, pattern matching, signal strength compression algorithms, and artificial neural networks.

Prototype Construction

We at GSTA are firm believers in using our empirical and computational results and to inform working prototype designs.

Examples of our demonstrated prototyping abilities include:

- 3D printing designs and collaboration with foundries for production

- Low-rate initial production (LRIP) designs for RF and microwave systems

- Microcontroller code production

- Matlab and executables creation
