Abstract The SUSAN filtering and its improved algorithm are introduced into for InSAR inteferogram filtering. The effects of the SUSAN and its improved algorithm are compared with that of the Goldstein filter. The experimental results with real data show that the proposed algorithms are superior to Goldstein filter, and make the improvement of 71.7% to 82.6% on Goldstein filter in reducing phase residual. The SUSAN and its improved algorithm, especially the latter,can not only suppress of interference noise better, but also keep the edge information of interferogram.
