Research Program
Scale and geometry
How does time-reversal compensation perform at the range and wavelength
scales and target sizes envisioned for sub-surface GPR?
Clutter rejection
How does extraneous targets degrade performance of time-reversal algorithms?
Data acquisition
How does the use of CDMA or similar methods for acquiring the multi-static
data matrix affect time-reversal compensation?
Phased array issues
How many separate antenna elements are required for adequate time-reversal
compensation?
Sub-surface
Can the background Green functions for the sub-surface be estimated from
first arrival backscatter data or conventional diffraction tomography?
Future Work
Finish simulation program
Include sub-surface interface
Employ extended target
Include clutter targets
Compute eigenvectors and eigenvalues for realistic parameters
