High-Resolution Inverse Synthetic Aperture Radar Imaging and Scaling With Sparse Aperture

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
In high-resolution radar imaging, the rotational motion of targets generally produces migration through resolution cells (MTRC) in inverse synthetic aperture radar (ISAR) images. Usually, it is a challenge to realize accurate MTRC correction on sparse aperture (SA) data, which tends to degrade the performance of translational motion compensation and SA-

Performance limits for maritime Inverse Synthetic Aperture Radar (ISAR) [PDF]

, 2013
The performance of an Inverse Synthetic Aperture Radar (ISAR) system depends on a variety of factors, many which are interdependent in some manner. In this report we specifically examine ISAR as applied to maritime targets (e.g. ships). It is often difficult to get your arms around' the problem of ascertaining achievable performance limits, and yet ...
