CIST: An Improved ISAR Imaging Method Using Convolution Neural Network
Remote Sensing, 2020 Compressive sensing (CS) has been widely utilized in inverse synthetic aperture radar (ISAR) imaging, since ISAR measured data are generally non-completed in cross-range direction, and CS-based imaging methods can obtain high-quality imaging results ...

Velocity-ISAR: On the application of ISAR techniques to multichannel SAR imaging [PDF]
2015 IEEE Radar Conference (RadarCon), 2015 The U.S. Naval Research Laboratory (NRL) Multichannel Synthetic Aperture Radar (MSAR) consists of multiple receive channels arranged along the flight direction and is unique in its ability to measure and correct for radial motion at each pixel in the scene. A well-known algorithm for performing MSAR imaging, and which have we applied for the first time
