Multipole Theory and Algorithms for Target Support Estimation

Figure 12

Improved boundary of the minimum source region, which essentially coincides with the true target support, corresponding to three test origins: (𝑥=2,𝑦=2), (𝑥=0,𝑦=10), and (𝑥=0,𝑦=0). Also shown is the contour plot of the amplitude of the backpropagated field associated to the field data.
