Investigating shallow water bottom feature using SAR data along Gulf of Khambhat, India

SAR Bathymetry Review and Its Possibility Implementation in Indonesia

“…Radar method In remote sensing, not only passive systems are developing. Active system remote sensing, such as SAR, is also experiencing development (Brusch et al, 2011;Huang et al, 2022;Julzarika et al, 2021;Ma et al, 2021;Rajput et al, 2021;Tarikhi, 2012). Radar methods utilize microwaves for determining water depths, consisting of Radar Altimetry and SAR techniques.…”

“…Active remote sensing, particularly SAR, has been catching up with its predecessor, passive remote sensing. In addition to optical images, SAR images, which are also a remote sensing technology, have been investigated for bathymetric studies (Brusch et al, 2011;Huang et al, 2022;Julzarika et al, 2021;Ma et al, 2021;Rajput et al, 2021;Tarikhi, 2012;Wensink & Alpers, 2014). Active remote sensing data is commonly referred to as radar images.…”

“…SAR is an active remote sensing that utilizes microwaves. SAR can be an alternative method for determining water depth (Bian et al, 2020;Rajput et al, 2021). The primary use of Synthetic Aperture Radar (SAR) data in acquiring bathymetry is conducted indirectly, as SAR images cannot directly penetrate the water to measure the depth of the underwater bottom topography.…”

Huang & Fu, 2004;Julzarika et al, 2021;Mishra et al, 2014;Rajput et al, 2021;Song et al, 2021;Tarikhi, 2012); North America (Ma et al, 2021;Tarikhi, 2012); Australia (Brusch et al, 2011;Pleskachevsky et al, 2011); and Africa (Ma et al, 2021). In Asia, study locations for SAR Bathymetry are distributed across several countries, such as China, India, and Indonesia, as depicted in Figure 9.…”
