Abstract
We present a new approach to the problem of detecting point
diffractors from active source surface seismic data. We formulate an
optimization problem in the configuration space of possible collections
of scatterers and construct a birth-and-death spatial dynamic, which
converges to the optimal solution. By design, this dynamic does not
have resolution limits typical of migration based techniques, which
allows for subwavelength sensing.
