Margaret Cheney, Department of Mathematics at听欧美口爆视频 State University, will talk, "Passive Source Localization"
This talk introduces the problem of localizing electromagnetic sources from measurements of their radiated fields at two moving sensors.听 听
Two approaches are discussed, the first based on measuring quantities known as 鈥渢ime difference of arrivals鈥� and 鈥渇requency difference of arrivals鈥�.听This approach leads to some interesting geometrical problems.听听
The second approach, a synthetic-aperture approach, is more promising but also involves some unsolved problems.听 听
