Using numerical scattering simulation of the BART (bidirectional analytic ray tracing method), an angular sequence of high-resolution 2-D ISAR (inverse synthetic aperture radar) images of a space target is produced. The Kanade-Lucas-Tomasi (KLT) feature tracker is then adopted for extracting feature points and matching all angularly consecutive ISAR images. 3-D positions of those featured points can...
