Singaporean Students’ Research Seeks to Advance Detection

Tan Chew “Eric” Kung, right, work on their passive, hybrid radio frequency (RF) intercept system in Spanagel Hall’s anechoic chamber, Aug. 9. The international students’ efforts to miniaturize RF components have promising possibilities for deploying on future, small autonomous vehicles.

“We believe the most significant advancement to consider is the increased capability of the microwave-photonic direction finding system to estimate the angle of arrival for low probability of intercept signals,” the duo explained.

Under the direction of NPS Department of Electrical and Computer Engineering Professor Dr. Phil Pace, director of the university’s Center for Joint Services Electronic Warfare, the team’s ongoing research increased signal resolution by combining off-the-shelf components into a compact, lightweight package, resulting in an improved performance of locating the position of an enemy transmitter while maintaining a stealthy profile.

“C.K. and Eric have done an amazing job sorting out the best optimization techniques to see these types of signals. They still have one more set of results to determine the sensitivity of the receiver by testing for the minimum discernible signal,” said Pace.
