Delph Sonar

Complete and highly productive geophysical software designed to easily and accurately perform SSS and SAS surveys.
More information


Delph Sonar is a complete acquisition, processing and interpretation software package designed to easily perform accurate and productive side-scan sonar (SSS) and synthetic apperture sonar (SAS) surveys. Providing an optimal QC at any stage and relying on Delph powerful workflow and ease-of-use, SSS and SAS mapping has never been so fast.


Delph Sonar acquisition interfaces with most analog and digital SSS and SAS. With a dedicated interface for each, it provides a unified data logger to record raw data in industry standard XTF format.


Delph Sonar interpretation is a dedicated tool for processing, analyzing and mapping any SSS and SAS data. Highly productive, it embeds high-level processing and benefits from Delph batch processing and mosaicking capabilities. The 2D profile view and 3D geographic visualization provide global QC and fast integration with other data types.
