Mānoa College of Engineering’s Hawaiʻi Center for Advanced Communications has received a $1.14 million research grant from the U.S. Office of Naval Research to improve reliability of military radar and wireless communications in diverse and challenging environments. Assistant Professor Zhengqing Yun and colleagues from HCAC will work with experts at SPAWAR Systems Center Pacific to investigate radio wave characteristics in complex, hostile and dynamic environments, such as heavily built urban areas, rugged mountain regions, sea-land transitions and over-the-horizon scenarios.

Wireless communication is dependent on radio waves to carry messages. In a built-up urban area, buildings and vehicles cause scattering that interferes with the transmission and receipt of messages, and creates areas that lack connection (cold spots).

Understanding this complicated wave propagation procedure is a key step in designing reliable wireless communications systems. The challenge in predicting wave propagation is significant, because it requires developing advanced computer software and carrying out extensive experiments.

The project will help the military rapidly establish reliable wireless communication networks in urban and other complex propagation environments by providing a unified application software package that performs equally well in diverse scenarios. Industries will also benefit from this research by using developed software tools in establishing better wireless systems.

“The collaborative environment at HCAC and availability of state-of-the-art research facilities provide significant opportunities for attracting federal funding and industry sponsorship,” says Yun.
