Reverse time migration algorithm for detection of buried objects in time domain

We have implemented an algorithm based on FDTD method, which achieves the reverse time procedure of electromagnetic waves. A convolution product has to be realised between this reverse wave and the incident signal that propagate in this medium without diffracting objects. The results provide high ac...

Description
Summary:We have implemented an algorithm based on FDTD method, which achieves the reverse time procedure of electromagnetic waves. A convolution product has to be realised between this reverse wave and the incident signal that propagate in this medium without diffracting objects. The results provide high accuracy in the objects localization even with only one multisensor measure. Moving the radar at the top improves the resolution. So this method is well suited for exploiting multisensor radar measurements.
