Semiparametric constant false alarm rate method for radar and sonar images
Electronics Letters, Volume 60, Issue 5, March 2024.This study proposed a novel constant false alarm rate (CFAR) method based on Gaussian mixture model (GMM). The reason for starting this work is that some new polarimetric detectors and the high‐resolution cases may lead to the failure of traditional parametric model.

A CTFM synthetic aperture sonar
, 1989 This thesis describes the theory and operation of a seafloor imaging Synthetic Aperture Sonar (SAS), based on broadband Continuous Tone Frequency Modulation (CTFM). Narrowband synthetic aperture techniques are reviewed, and some of the limitations of

The utility of synthetic aperture sonar in seafloor imaging [PDF]
, 2005 Synthetic Aperture Sonar (SAS) is a high-resolution acoustic imaging technique which is an extension of normal sidescan sonar imaging. The cross-range (azimuthal) resolution in real aperture sonar is dependent on distance to the illuminated scene and ...

An Introduction to Synthetic Aperture Sonar (SAS)
, 2015 While conventional sidescan sonars are commonly used for seafloor imaging, they suffer from some basic limitations. Firstly, the imaging resolution, or the system\u27s ability to distinguish closely spaced objects, is not constant but degrades with range.
