Two-dimensional deceptive jamming mitigation algorithm for SAR imaging using frequency diverse array
The Journal of Engineering, 2019 The synthetic aperture radar (SAR) may be threatened greatly by the deceptive jamming within its main-lobe. To tackle this problem, a two-dimensional self-adaptive frequency diverse array (FDA)-based SAR processing scheme is proposed in this study ...

Forward-Looking MIMO-SAR for Enhanced Radar Imaging in Autonomous Mobile Robots
IEEE Access, 2023 Synthetic aperture radar (SAR) techniques are commonly used in spaceborne and airborne side-looking radar imaging applications, where the relatively high platform speeds enable the formation of very long synthetic apertures, which provide images with ...

Fractal parameters and SAR images [PDF]
2008 IEEE Radar Conference, 2008 The fractal geometry proved to be the most appropriate mathematical instrument in describing natural scenes, by means of few effective and reliable geophysical parameters. In this paper we describe a complete processing chain for the retrieving of SAR image fractal parameters and for change detection purposes.
