Decision Aid for Risk Evaluation (DARE) Version 2.1 User Guide.  Karna Bryan, Elizabeth P. Signell, Nicole Arsenault. NURC-SP-2006-001. March 2006.

Decision Aid for Risk Evaluation - DARE - is a NATO Experimental Tactic (EXTAC 858) for assessing the risk to transiting vessels after Maritime Mine Countermeasures (MCM) have taken place. The NATO Undersea Research Centre sponsors the EXTAC and had been responsible for the last several versions of the DARE software. This document is the User Guide for the current version of the software, DARE 2.1 and will help both new and experienced users to better utilize the software.

Espresso(m) - User Guide. Gary L. Davies ; Elizabeth P. Signell. NURC-SP-2006-002. March 2006.

Trials conducted over several years with the NATO Immediate Reaction Forces have demonstrated that Command Teams experience problems in quantifying minehunting sonar performance, especially in areas where the environmental factors combine with low target strength mines to produce difficult minehunting conditions. Inexact performance predictions result in poor evaluations of mine clearance which in turn lead to inaccurate assessments of remaining risk to follow-on forces in the channel or area. Espresso (Extensible Performance and Evaluation Suite for Sonar) has been developed to provide a standard NATO minehunting sonar performance prediction tool that interfaces directly with the NATO MCM planning and evaluation tactical decision aid (MCM EXPERT) to support planning and evaluation of minehunting operations. This User Guide describes the military version of Espresso (Extensible Performance and Evaluation Suite for Sonar).

Espresso - Scientific User Guide. Gary L. Davies ; Elizabeth P. Signell. NURC-SP-2006-003. March 2006.

This User Guide describes the scientific version of Espresso (Extensible Performance and Evaluation Suite for Sonar). Espresso is a NATO minehunting sonar performance prediction tool that exists in two versions, one intended for scientific use and the other for military use. The scientific version of Espresso provides greater flexibility than the military version, including the ability to select sub-models and view the results of any sub-model. This user guide addresses the user interface for Espresso and describes the underlying software models and data output options available within Espresso. There is a separate user guide for the military version, Espresso(m).

FESTA User Guide ß-Version 1.0. NURC-SP-2006-004. June 2006.

The detection and classification of low target strength mines, especially when these are buried or masked by vegetation, is a major challenge for the current MCM SONAR technology. Low frequency SONAR techniques, in the range below 50 kHz for typical mine-like objects, can add value to the current minehunting technology by improving the detection and classification capabilities. FESTA is the 3-D finite-element structural acoustics code developed at the NATO Undersea Research Centre for modeling the scattering of SONAR signals from elastic targets located in, on or near the seabed. The tool is based on state-of-the-art hierarchic finite element technology, which offers the flexibility of increasing the polynomial order and/or the element mesh density anisotropically along preferred directions in the computational domain. This report documents the features available to the user of FESTA -1.0 via definitions of the input stream file structure and syntax, and via simple examples. The setup of a more complex example, which reproduces some broadband target scattering computations presented in the literature, completes the tutorial.

ASTPA User Guide. Strode, C. NURC-SP-2006-006. September 2006.

The Area Search Tactical Planning Aid (ASTPA) may be used to provide a quantitative assessment of a pre-defined search plan in terms of the ability of the search platforms to detect a target or to clear a given area. Alternatively the model may be used to generate optimized search plans for a given scenario. The model simulates realistic target behaviour in terms of transiting, localising and avoidance tactics and displays the behaviour so as to increase the situational awareness of the search platform. The following user guide details the generation and editing of scenarios within ASTPA.
