Researchers from the Electrical and Electronics Engineering Institute of the University of the Philippines Diliman (EEEI-UPD) are looking to enhance current capability in the Philippines in the sustainable operation of radars. “We’re investigating opportunities for enhancing the radio frequency (RF) front-end and radar signal processing blocks or sub-systems of such systems,” the project team explains. These research activities and outputs are intended to help spur the Philippines towards achieving technological independence in this area in the near future.
In 2013, the team visited the radar sites of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA)in Aparri, Cagayan and Guiuan, Eastern Samar. “We were able to take apart a decommissioned radar unit for electrical testing and characterization,” they recount. “At present, we’ve produced a handbook with detailed descriptions of radar operation, functions of various sub-modules and component test plans intended for PAGASA personnel.”
The results of radio frequency testing and characterization of the radar receiver front end are also currently being compiled. The team operated the radar in Guiuan, Samar in order to obtain signal returns, which were then digitized and fed into signal processing blocks being developed by EEEI researchers and engineers. These processing primarily involve filtering, noise reduction and clutter suppression techniques. Comparisons will be made with readings from the actual radar.
The project is funded by the Philippine Council for Industry, Energy and Emerging Technology Research and Development of the Department of Science and Technology (DOST-PCIEERD) and the University of the Philippines Diliman.
