The goal of this task is to provide the capability of building new ship and small watercraft target models that include wake effects for the fleet Target Acquisition Weather Software (TAWS). TAWS is a strike warfare tactical decision aid developed by the Air Force Research Laboratory (AFRL) for joint Air Force, Army, and Navy use. The purpose of TAWS is to predict the performance of electrooptical weapons systems for a given set of targets, backgrounds and forecast weather conditions. The TAWS software calculates target-background contrasts to predict detection range, recognition range, lock-on range, optimum approach azimuth, best altitude, and thermal crossover times for a large variety of airborne sensors. The Navy is leveraging on this multimillion-dollar Air Force effort and steering feature development to be more inline with the needs of the Navy and the marine environment. 1.2. Presently, there are only two ship targets in TAWS and several more are needed. However, the current target building software, MuSES (Multi-Service Electro-optic Signature) has limited ship-modeling capability. This task will upgrade the capabilities of MuSES to build new ship targets that include wake effects. The effects of the turbulent wake, Kelvin wake, and breakwater against the surrounding water background are often a major factor in determining detection range, especially for small fast boats. It is crucial that new boat targets be added to complete the TAWS target menu and it is also crucial that the wake effects be included in these targets so ships of all sizes and speeds can be targeted. 1.3. This task is to research, design, develop, integrate, implement, debug, and test a new ship modeling capability for TAWS and the MuSES thermal engineering package. ThermoAnalytics, Inc, developed the MuSES (http://www.thermoanalytics.com/muses/index.html) standalone engineering package, and the thermal post-processor module from MuSES is integrated into the fleet TAWS product to perform the target-background thermal contrast calculations. This direct connection between TAWS and MuSES requires using the ThermoAnalytics MuSES engineering software to build new targets. This also means that any developer involved in this upgrade must be familiar with the software implementations of both TAWS and MuSES. 1.4. The MuSES target-background contrast module represents the target as a CAD-like composite wireframe of thermal nodes that interact with adjacent nodes and the surrounding atmosphere. This task will continue this concept and upgrade the ship target building capability to accounting for wake effects. The wake effects include the bow wave, stern wave, and the area between the resulting characteristic V-shaped wavefront boundary. The wake area may contain breaking waves, whitewater areas, Kelvin waves, wind waves, and turbulence fields. These phenomena will vary and dissipate depending on parameters, such as, ship speed, wind speed, viscosity and sea state. It is left to the developer to decide the best approach to the problem because runtimes and complexity of inputs must be minimized in consideration of the user. Any combination of first-principles computational fluid dynamics, statistics, or empirical fits may be used to describe the wake field depending on what makes the most sense in maintaining accuracy, usability, and efficiency. The contractor must have a theoretical understanding of the MuSES algorithms, coding, and concept of operation along with an understanding of the TAWS implementation and user-requirements. 1.5. This task must coordinate with the overall TAWS development schedule. Version 4.0 of TAWS is scheduled for release in March 2002. This task must therefore be completed by December 31, 2001 in order to have new targets and changes integrated into the final release of TAWS to the fleet. 2.0 SCOPE. This work relates to both the TAWS and MuSES software products. The goal is to provide new watercraft targets including the wake effects that run in TAWS. This involves making necessary modifications to MuSES to be able to build new watercraft targets that include wake effects over various ship speeds and operating conditions, and if necessary, modifying TAWS to run the new targets. This task involves researching wake modeling options, such as, first principles computational fluid hydrodynamics, statistical models, scaling pre-computed solutions, and empirical representations, and then selecting the approach best suited for TAWS to calculate range predictions in an efficient user-friendly manner. Two new ship targets, a small fast boat (such as a MK-V special operations boat) and a navy destroyer (such as a DD-965 class destroyer) along with the wake effects will be built under this task for testing in TAWS against measured data. 3.0 TECHNICAL REQUIREMENTS. Research options for modeling wake effects, such as parametric computational fluid dynamic models, statistical solutions, and empirical regression models. Determine the best approach to include significant wake effects as part of the water-operated target models in MuSES and TAWS. 3.2. Develop a modular object oriented computer code that makes MuSES capable of building watercraft targets that can be used with both MuSES and TAWS, and include significant wake effects as part of the target. Because TAWS is a user-interactive fleet product, the new targets will not substantially extend runtimes and not degrade the present overall accuracy of TAWS. The model operation in TAWS will utilize existing input parameters as much as possible and any newly required inputs will be easily obtainable by the user (such as: meteorological forecasts, estimated ship speed and heading, and sea state and sea surface temperature) with typical default values given to start. Parameters that may be confusing to the user, such as Reynold's numbers, Froude numbers, ship physical and chemical properties, specifications, etc. may be required for the initial target development in MuSES, but will be transparent from the user's point of view in TAWS. 3.3. Develop a Graphical User Interface for creating/editing/displaying the Wake Model in MuSES. In order for the Wake Model to be useful to the user, an easy-to-use interface must be constructed that enables user inputs and makes possible easy error checking of results. The GUI will include the means for constructing the water terrain as well as pre (geometry) and post (radiance) visualization. 3.4. Demonstrate the new capability by building two new boat targets that include wake effects. The two targets will be a DD-965 class destroyer (http://www.fas.org/man/dod-101/sys/ship/dd-963.htm) to demonstrate the wake dynamics of a water-displacing vessel and a Mark V special operations speedboat (http://www.fas.org/man/dod-101/sys/ship/mark_v.htm) to represent the wake dynamics of a hydroplaning type craft. SSC-SD will provide test cases to exercise these new models. 3.5. The deliverables will include: (1) a complete and easily installable working version of MuSES and TAWS with the new wake handling capabilities and two new boat targets, (2) test cases of the two new targets, (3) software source code and modules with instructions for compiling, (4) software documentation for operating MuSES, and (5) a report with technical descriptions of the algorithms used and work accomplished. All delivered software modules will be Year 2000 compliant. 3.6. Provide technical problem support and bug fixes for six months following final acceptance of software. 4.0. GOVERNMENT FURNISHED EQUIPMENT/MATERIALS. None. 5.0. TRAVEL. One trip, 5 days to SPAWAR Systems Center, San Diego, for code review and preliminary validation against measured data. 6.0 OTHER. 6.1.
