Mathematics Colloquium

Imaging with correlations

Speaker: George Papanicolaou, Stanford University

Location: Warren Weaver Hall 1302

Date: Monday, May 7, 2018, 3:45 p.m.


After a brief introduction to imaging and some commonly used imaging methods, such as migration in geophysical exploration, sonar and radar imaging, I will introduced correlation-based imaging. It is a passive form of imaging where the illumination is not known, it is asynchronous and often opportunistic. One can still image coherently as if the illumination was known, and this is what correlations can do. Examples from geophysics and, more recently, from satellite imaging with radar illustrate what can be achieved and what some challenges are in the near future.
