SIAM Journal on Imaging Sciences, Volume 13, Issue 1, Page 108-140, January 2020.
We consider the inverse scattering problem for sparse scatterers. An image reconstruction algorithm is proposed that is based on a nonlinear generalization of iterative hard thresholding. The convergence and error of the method was analyzed by means of coherence estimates and compared to numerical simulations.

逆散射的非线性迭代硬阈值

SIAM影像科学杂志，第13卷，第1期，第108-140页，2020年1月。
我们考虑稀疏散射体的逆散射问题。提出了一种基于迭代硬阈值的非线性概括的图像重建算法。通过相干估计分析了该方法的收敛性和误差，并与数值模拟进行了比较。
