Compressed sensing methods are significantly improving next-generation radar systems.

Dr. Petros T. Boufounos was elevated to IEEE Fellow in 2022 for his work in compressed sensing technology through a broad-ranging approach that has transformed the way we think about data acquisition. Compressed sensing methods enable significant improvements in both efficiency and quality in how we sense and measure the environment. The core idea is that the signal being measured has important structural properties that can be leveraged during acquisition. With the increase in available computing power, it has become possible to use models of these signals (such as sparsity, manifold structure, or other forms) to overcome classical limits on acquisition efficiency and performance.

He has conducted extensive research on understanding how quantization affects compressed sensing systems, determining their performance limits, and identifying how those limits can be reached. He has also developed groundbreaking methods for processing compressed signals without reconstruction, enabling information to be extracted directly from the compressed measurements. In addition, his research on applications of compressed sensing methods has greatly advanced radar systems, particularly synthetic aperture radar (SAR). SAR is a remote sensing technology that uses radar mounted on aircraft or satellites to generate high-resolution images of large geographic areas. These research outcomes are slated to be incorporated into next-generation satellites and their SAR systems.

Thinking long term, Petros sees great potential in the quantum domain which is now leaving in the realm of basic scientific discovery. Processing, modeling, sensing, and computing using quantum systems are gradually becoming more accessible and very promising as technology evolves. He aims to continue developing technologies in this area in anticipation of a future where quantum systems are widely available.

His message to young researchers is that "It is important to follow your passion and your interest in research. It is also important to steer your passion toward making an impact on the world and the scientific community. Solving impactful problems that make a difference is very fulfilling."
