Improved Frame-Selection Scheme for ISAR Imaging of Targets in Complex 3-D Motion
IEEE Sensors Journal（2018）
Abstract
When a target is in complex three-dimensional (3-D) motions, inverse synthetic aperture radar (ISAR) images cannot be obtained with any motion compensation algorithms. To address this problem, phase nonlinearity can be used to select imaging frames where target 2-D motion is dominant enough to obtain focused ISAR images. Conventionally, adaptive joint time frequency (AJTF) and particle swarm optim...
