Multipole Theory and Algorithms for Target Support Estimation

Figure 13

Computed boundary of the minimum source region based on test origins (𝑥=2,𝑦=2), (𝑥=0,𝑦=10), (𝑥=0,𝑦=0), (𝑥=−2,𝑦=2), and (𝑥=−10,𝑦=0). Also shown is the contour plot of the real part of the incident field due to the point source at (𝑥=−4,𝑦=0) and the analytical boundary of the minimum source region (small circle in the figure) which ignores the finite-dimensional nature of the field under realistic noise and perturbations.
