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 data can provide the command with information such as best evasion depth, likely target depths, bearing and optimum sonar and platform positioning. The system is fully range-dependent, the embedded models have been independently verified by the UK MoD and is their system of choice.

- Global port locations and ocean place names
- User defined area boundaries
2D Radial Sonar Range Prediction
Distance Measuring Tool
WADER provides both flat plan and vertical slice propagation loss displays. The former are displayed on the Main Screen using colour coded ‘blobby radials’ which are plotted at 15 degree (or greater) intervals.
Each set of radials can be configured independently in terms of sonar type, frequency, depth and Figure of Merit (FOM).
This feature allows users to overlay distance markers on their chart, thus enabling the measurement of non detection zones and other features.
The distance markers can be toggled on and off.
Click on the images below to view some other features on the Main Screen.
3D Dynamic Area Display
The 3D Dynamic Area Display allows users to create an interactive 3D model of the seabed at any location.
This model can be augmented with a 3D rendering of Probability of Detection (PoD) from the surface to any depth down-to the seabed, maximum range circle and user-defined waypoints.
MultiPlot Tool
Calculate Probability of Detection (PoD) ranges for multiple platform types, each of which can possess different sonar parameters.
Use the MultiPlot tool to aid in task group deployment, particularly if resources are limited.
Multistatic Acoustics
Multistatic Grid Editor
WADER includes a number of pre-defined tranducer patterns which can be augmented with user defined patterns.
The Multistatic Grid Editor has been updated to make the selection of different transducer patterns easier - this significantly improves the selection experience for tablet users.
The MSA is capable of predicting thousands of different transmitter/receiver position combinations via a 9x9 user-defined grid pattern (up to 81 transmitters and 81 receivers can be activated).
The angle of offset and spacing between the transducers can be easily adapted using the controls.
Chart Overlays
WADER allows the user to overlay many different elements on any chart. Below are just a few examples.
Main Screen
- Sediment data charts
- Ambient noise & weather data (with 3rd party product access)
- Global port locations and ocean place names
- User defined area boundaries
Environment Screen
The Environment Screen allows users to edit both the track and operational environment. Users upload and manage their own (measured) environmental 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 both manually or automatically with the track for use in the analysis screen.
Cross Section Viewer on the Environment Screen
WADER is range dependent and the cross section viewer enables the user to view the temperature, salinity, sound speed, potential density and buoyancy frequency along their chosen track.
Each set of radials can be configured independently in terms of sonar type, frequency, depth and Figure of Merit (FOM).

DTSV Automerge
Users are able to upload their own profiles in DTSV onto both the WADER Main Screen and Environment Screen. These could be your own climatological datasets or bathy data of the day. Once uploaded, the user is able to auto merge their own profiles with the climatology.
Each dot on the left hand chart represents a user's profile. In this case the profiles along the track have been auto-merged from 17km to the end of the track.
Users can also upload their own profiles within the Environment Screen in CPD, JJYY or JJVV format. Other formats may be incorporated; please contact OAD to discuss your requirements.
Profile Viewer
The profile viewer enables the user to compare their own uploaded profiles with the embeded climatology (WOA 2018 and 2013). In the example to the right the user profile is red and the climatology is black.
WADER supports up to 102 points within a profile for higher fidelity.
Environment Screen
The Environment Screen allows users to edit both the track and operational environment. Users upload and manage their own (measured) environmental 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 both manually or automatically with the track for use in the analysis screen.
Analysis Screen
The Analysis Screen is where the user conducts detailed Propagation Loss Analysis (Proploss). The screen has a Probability of Detection (PoD) diagram (PODgram), Propagation Loss graphic and Ray-Trace diagram. Users can also display an Environmental Impact Assessment (EIA chart), best
source depth and intensity distribution chart. In-situ adjustments can be made for (amongst others) reverberation losses, target/source depths & sonar beam angle. Parameters for shipping, sea state and ambient noise are accounted for in the embedded Figure of Merit (FOM) calculators.

Annual Upgrade Plan
With the nature of technological change, it is essential to keep all equipment and software up-to-date to maintain operational readiness. WADER‘s Annual Upgrade Plan (AUP) meets this requirement with minimal impact on the user.
All AUP customers will receive at least one software upgrade per year and can be guaranteed assistance whenever or wherever they may be.
WADER V8.4 - released in September 2022.
Click on the images below to view the main features included within the WADER V8.4 upgrade.
Batch Mode
WADER has been designed to conduct deep analysis of individual sensors, however there are times when it is helpful to compare the performance of multiple sensors within an environment, or different configurations of a single sensor.
Batch Mode has been developed to assist in this type of analysis by enabling users to pre-define a list of sensors and/or metrics. Once created, the user can use Batch Mode to process each sensor configuration for the environment and then toggle through the results to compare probabilities of detection.
Batch Mode
Custom Contours
Users can highlight up to three contour depth lines, specifying the depth and colour of each. Areas shallower and/or deep than the contour can be flood-filled.
Chart with three custom contours applied
Range Rings
In addition to the legacy range read out options, users can now display range rings at major (and minor) intervals to help assess probability of detection ranges.
Range Rings set as 10km intervals
Sonar Editor
The Sonar Editor is where users build and save their own sonars for use in range predictions. Sonars can be grouped into Sonar Suites for use in different operations.
WADER is supplied with a comprehensive set of fictitious sonars – SPUTS – for training purposes.
