Point detection in textured ultrasound images
(2023-02-26)
Detection of point scatterers in textured ultrasound images can be challenging. This paper investigates how four multilook methods can improve the detection. We analyze many images with known point scatterer locations and ...
Adaptive phase estimation filter in long range synthetic aperture sonar interferometry
(2023-05-15)
Synthetic aperture sonar (SAS) interferometry is a technique for very high resolution imaging and mapping of the seabed. In SAS interferometry, the seabed depth estimation performance is a function of the system, the ...
MIMO synthetic aperture sonar: Benefits and limitations
(2023-01-16)
The use of Multiple Input Multiple Output (MIMO) orthogonally coded waveforms sharing the same bandwidth, has the potential to increase area coverage rate in synthetic aperture sonar (SAS). The disadvantage is cross-talk ...
