Paper Abstract

Imaging of land mines using signal of a light-weight GPR is considered as an inverse problem for a Helmholtz-like equation. This equation is derived from Maxwell's system. The inverse problem consists in recovery of electrical permittivity and conductivity of a target(s) using multi- frequency measurements of the back-reflected signal. A novel method of solution is proposed. A crucial advantage of this algorithm over many traditional ones is that it avoids entirely the problem of local minima, since it does not use a least squares cost functional.
