Boundary-Condition-Enhanced Linear Sampling Method Imaging of Conducting Targets From Sparse Receivers

We present a formulation of the linear sampling method (LSM) for imaging conducting targets using a spatially sparse set of receive locations. The technique mitigates the lack of spatial channels by disciplining the LSM solution to achieve the correct electric field boundary conditions on an estimate of the target boundary. As the true target boundary is unknown, we use an iterative procedure to j...
