Microlocal ISAR for Low Signal-to-Noise Environments [PDF]
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 ...

Impact and Compensation of Rainfall Propagation Effect on Pol-ISAR Imaging of Parabolic Antenna
Orientation is an important parameter to identify the working status of a parabolic antenna. Polarimetric inverse synthetic aperture radar (Pol-ISAR) is an effective approach to sense the parabolic antenna, but the imaging process may be seriously ...

Long-Time Observation-Based Multiattitude ISAR Imaging Method for Moving Ships
Long-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– ...

An improved inverse synthetic aperture radar range alignment method based on maximum contrast
Inverse synthetic aperture radar (ISAR) is an important tool for non-cooperative ship imaging, and one key step of ISAR imaging is range alignment. To achieve the range alignment with high precision, efficiency and robustness, an improved ISAR range ...
