The top panels show conventional radar profiles capturing the structure geometry (with flow oriented primarily left to right, with components into, ⨂, and out of, ⨀, the page). The lower panels show along- and across-track direction-of-arrival images for the trace indicated by the vertical dashed line in their associated top panels. Best-fit directions-of-arrival (indicating layer slopes for specular layering) are shown in red, offset by red arrows from the true image maxima to facilitate comparison.
