The problem of fleld focusing onto a target location in an unknown scenario is considered. In particular, we devise an adaptive procedure in which flrst an image of the unknown region where the target point is located is formed via the linear sampling method (LSM). Then, the LSM result is used also to deflne the excitations coe-cients for the array elements needed to focus the fleld. This novel approach to focusing is described and tested with numerical examples.
