Webened the significance of the gridding effect. This inspired us to introduce ANM into TomoSAR to achieve a much more robust three-dimensional imaging with insufficient samples. However, the price of ANM is the huge computational com-plexity brought by SDP, which limits the application of ANM and makes it infeasible in practice. Tackling this ...
