Abstract:
|
Microwave tomographic imaging technology using a
bifocusing operator has been developed in order to detect the internal
voids/objects inside concrete structures. The imaging system
consists of several cylindrical or planar array antennas for transmitting
and receiving signals, and a numerical focusing operator
is applied to the external signals both in transmitting and in receiving
fields. An imaging algorithm using numerical focusing operator
was developed, which allows the recovery of a two-dimensional
object from its scattered field. Numerical simulation demonstrated
that a subsurface image can be successfully reconstructed
by using the proposed tomographic imaging technology. For the
experimental verification, a prototype planar antenna array was
fabricated and tested on a concrete specimen. |
