SWATHplus
Sonar
SWATHplus
is a wide swath sonar system for surveying underwater surfaces. It
acquires high density bathymetry and sidescan data. Processed data
output includes Digital Terrain Models and sidescan images. It is
equally well suited for use at sea, and for inland waterways and lakes.
SWATHplus surveys to water depths of 350 metres. It is particularly
efficient in shallow water, and is low-cost, compared with similar sonar
systems.

The advantages of SWATHplus include:
-
Very wide swath width, especially in shallow water, giving excellent survey
productivity. Ratios of swath width to water depth typically exceed 15:1,
rising to over 20:1 in less than 10m depth.
-
Portability: the system is small, light (<5kg for the 468kHz version), and
consumes little power (<15W apart from the computer).
-
High Resolution and Accuracy: the system records many more data points than
competing technology, whilst maintaining survey accuracy to international
standards, including IHO S44 Special Order. SWATHplus can be configured to ping
simultaneously on both sides, thus doubling survey productivity in comparison
to similar systems.
-
Simultaneous Side Scan: SWATHplus produces sidescan imaging data of a quality
on a par with any sidescan-only system, co-registered with the bathymetry.
-
Imaging Mid-water Objects and Structures: SWATHplus can detect objects in mid-
water and on the surface, as well as the bottom.
-
Cost of Ownership: system simplicity results in a low initial purchase price,
high reliability, simple maintenance and long service life.
