‘WADER is currently the best tool in terms of the widest range of capabilities and functionality. The operators also see it as being the best tool, with the best GUI (Graphical User Interface) and the most comprehensive training program.’
UK MOD Report, 2009

WADER is a comprehensive sonar range prediction and Global Ocean Information System which uses Global environmental data (sea state, water column and bathymetry) together with user-supplied acoustic parameters to generate propagation loss data & calculate sonar performance/probability of detection. Designed for operational users of all abilities, the data is generated in real time and displayed using clear graphics. Correct interpretation of the graphs can provide Command information such as best evasion depth, likely target depths and optimum sonar position. The system is fully range-dependent and the embedded models have been independently verified.

Using WADER

WADER is designed to provide comprehensive capabilities within a user-friendly package. The system shields the new user from the complexities of underwater acoustic range prediction while simultaneously providing the experienced operator with advanced options to perform detailed calculations without significantly increasing the workload or complexity.

The process is rapid, reliable and simple. It is controlled via four main screens (below).

WADER applications include: research, training, teaching, EIA, operational sonar performance prediction, anti-submarine warfare (ASW), pre- & post-mission acoustic analysis. For additional uses, see the applications page.

Main Screen

The Main Screen (right) is the starting point for calculations where users define their area of interest and add detail to the map display. The Main Screen renders the 2D sonar performance radial displays & provides access to 3D DAD.  In addition to the on-screen climatology data readouts, optional overlays include:

Sediment data charts

Ambient noise & weather data (with 3rd Party Product access)

Global ports locations and ocean place names

User defined area boundaries

Environment Screen

The Environment Screen (left) allows users to edit the track and operational environment. Users upload and manage their own (measured) environment profiles (salinity, SSP) from XBTs using time filters, edit the seabed properties and analyse the sound channel. The data is visualised using the seabed cross-section and profile charts.

High resolution water column profiles can be merged automatically with the tack for use in the analysis screen.

Analysis Screen

The Analysis Screen (right) is where the user conducts detailed propagation loss analysis. The screen has a probability of detection diagram, propagation loss graphic and ray-trace diagram. Users can also display an EIA chart, best source depth and intensity distribution chart.  In-situ adjustments can be made for (among others) reverberation losses, target/source depths & sonar beam angle.  Parameters for shipping, sea state and ambient noise are accounted for in the embedded FOM calculators.

Sonar Editor

The sonar editor is where users add their own sonar parameters for use in their range prediction processes. WADER is supplied with a set of fictitious sonars – SPUTS – for training purposes.

WADER has been developed over 20 years and the Graphical User Interface (GUI) is the result of OAD design effort and substantial feedback from informed users in the military and civilian research communities. With WADER there are no add-ons to purchase or hidden extras – every user has access to every feature of the program immediately. The product is regularly upgraded and upgrades are released as part of our Annual Upgrade Plan.
