$$
and \(L=120\) different positions of a single small scatterer on the circle of radius \(\lambda\epsilon^{-p}=100\),
\begin{align}\label{eq:scatterer-beta}
- \boldsymbol{y}_\epsilon^\ell = 100e^{i\theta_y^\ell}, \quad \theta_y^\ell = \frac{2\pi}{L}(\ell - 1 + \beta_\ell), \quad 1\leq \ell\leq L,
+ \boldsymbol{y}_\epsilon^\ell = 100e^{i\theta_y^\ell}, \quad \theta_y^\ell = 2\pi\beta_\ell, \quad 1\leq \ell\leq L,
\end{align}
- where \(\beta_\ell\) is drawn from the uniform distribution on \([0,0.1]\). Finally, we add some multiplicative white noise with amplitude \(\delta=\epsilon^p\epsilon^{q/2}=10^{-4}\) to the the near-field measurements (generating a matrix \(\widetilde{C}_\delta\)), and probe the medium on a \(100\times100\) uniform grid on \([-6\lambda,6\lambda]\times[-6\lambda,6\lambda]\).
