- Merge your own high-resolution data with global datasets
- 3D seabed & probability of detection rendering
- Multistatic (MSA) sonar performance prediction
- Multi-plot function for multiple on-screen calculations
- Sonar Parameters for Unclassified Training Systems (SPUTS) database & documentation
- Embedded Figure of Merit (FOM) calculator
- Reverberation model & reverberation data upload facility
- Wide variety of oceanographic reference chart types
- Customisable chart overlays
- Best Source Depth tool
- Stand-alone software – no web connection necessary
- Can be integrated into Command Management Systems (CMS)
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.

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.

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.
