Microlocal ISAR for Low Signal-to-Noise Environments [PDF]
, 2006 The problem of extracting radar target information from multi-aspect high-range-resolution data is examined. We suggest a new non-imaging approach that is based on microlocal analysis, which is a mathematical theory developed to handle highfrequency ...

Long-Time Observation-Based Multiattitude ISAR Imaging Method for Moving Ships
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingLong-time synthetic aperture radar observation facilitates the tracking and identification of moving targets. However, continuous changes in the attitude of a moving target during long-duration observations cause the azimuth signal’s time– ...
