Summary:
A modified focusing image technique based on a hyperbolic summation algorithm for through-the-wall radar system is introduced in this paper. The unavoidable ghost image of the hyperbolic summation can be suppressed using this modified algorithm. The 3-dimensional finite-difference time-domain (FDTD) method is performed to realize problem situation. The conventional hyperbolic summation blurs its raw image in the front area of a target, which may violate a causality principle. The final correction image satisfying the causality principle shows remarkable decrease of ghost image in comparison with the conventional hyperbolic image.
