Electromagnetic radar system developed by DOST and MSU-IIT

Researchers from the Mindanao State University – Iligan Institute of Technology (MSU-IIT) has developed an electromagnetic radar that accurately detects underground water features. 

The Electromagnetic Radar Technique for Water Detection Project Leader Dr. Olga Joy Gerasta shared that their innovation can detect groundwater with greater precision through the electromagnetic waves it emits.

This electromagnetic radar system has custom-designed antenna that sends radio pulses into a material. Then, its integrated computer records the strength and time required for the return of any reflected signals.

Various energy reflections from geological structures like a water table and buried man-made objects like pipes  are picked up by the system and stored on digital media. Gerasta’s team identifies these objects using artificial intelligence (AI).

The radar system works best on dry, sandy soil wherein targets can be detected at depths of more than 20 feet.

The final radar system design was tested and verified in controlled set-up in Taytay, Iligan City and Iligan City’s selected low, middle, and high elevation areas.

The development of the technology was funded by the Department of Science and Technology Philippine Council for Industry, Energy and Emerging Technology Research and Development (DOST-PCIEERD).

DOST-PCIEERD executive director Dr. Enrico C. Paringit underscored the significance of the innovations that MSU-IIT researchers achieved.

“As our groundwater supplies more than 50% of Filipinos’ potable water supply and 85% of piped water supply, this electromagnetic radar system will not only save us money, time, and effort in finding water sources, but it also allows us to easily map and monitor underground resources, plan efficient and safe ground excavation.” said Paringit.
