Ground-Based Synthetic Aperture Radar (GBSAR) has non-contact, all-weather, high resolution imaging and microdeformation sensing capabilities, which offers advantages in applications such as building structure monitoring mine slope deformation retrieval. The Circular Scanning (CS-GBSAR) is one of its newest developed working mode, the radar rotates around an axis a vertical plane. Such nonlinea...

Adaptive detection of multidimensional signals in the presence of interference with unknown covariance matrix is an expanding topic in a variety of scenarios ranging from radar/sonar to digital communication systems. In this paper we attack the problem of detecting a multidimensional radar signal, modeled as an unknown matrix, embedded in Gaussian noise with unknown covariance matrix, with the ...

Finding the edges between different regions in an image is one of the fundamental steps of image analysis, and several edge detectors suitable for the special statistics of synthetic aperture radar (SAR) intensity images have previously been developed. In this paper, a new edge detector for polarimetric SAR images is presented using a newly developed test statistic in the complex Wishart distri...

In this paper, constant false alarm rate (CFAR) detector-based approaches are proposed for interference mitigation of Frequency modulated continuous wave (FMCW) radars. The methods exploit the fact that after dechirping and low-pass filtering operations targets’ beat signals FMCW radars composed exponential sinusoidal components while interferences exhibit short chirp waves within a sweep. spec...
