Advanced techniques involving the simultaneous processing of multiple SAR acquisitions in time increase the number of locations where a deformation signal can be extracted and reduce associated error. Currently there are two broad categories of algorithms for processing multiple acquisitions, <jats:italic>persistent scatterer</jats:italic> and <jats:italic>small baseline</jats:italic> methods, which are optimized for different models of scattering. However, the scattering characteristics of real terrains usually lay between these two end‐member models. I present here a new method that combines both approaches, to extract the deformation signal at more points and with higher overall signal‐to‐noise ratio than can either approach alone. I apply the combined method to data acquired over Eyjafjallajökull volcano in Iceland, and detect time‐varying ground displacements associated with two intrusion events.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382825894415329920","@type":"Researcher","foaf:name":[{"@value":"Andrew Hooper"}],"jpcoar:affiliationName":[{"@value":"Nordic
