Direction-of-Arrival Estimation Methods in Interferometric Echo Sounding. [PDF]

Sensors (Basel), 2020
Nowadays, there are two leading sea sounding technologies: the multibeam echo sounder and the multiphase echo sounder (also known as phase-difference side scan sonar or bathymetric side scan sonar). Both solutions have their advantages and disadvantages,
