Modeling

The TSC team has extensive experience in the modeling and simulation of many Navy systems. The level of detail ranges from mathematical models to detailed simulations of complete systems.

TSC is particularly adept in simulating radar and other detection systems, sensor environments, and hardware stimulators. TSC’s simulations address several key US Navy radar systems, including the AN/SPY-1 family and the AN/SPQ-9B. TSC has also developed several important environmental simulations, including the AEGIS sea clutter model, a sea spike simulation, and a propagation and clutter tool (EMPCODE).

TSC’s AN/SPY-1 simulations include the Testable Component Environment (TCE), which has recently been accredited for Baseline 7 Phase 1C (Cruiser Modernization) testing. TCE is engineering software support code that runs the actual AN/SPY-1 tactical RCCP code in a desktop environment to simulate threat and environment scenarios, to exercise RCCP functionality (for debug and development), and to format data recording that can be read into both TCE’s and other, existing analysis tools. TCE’s fidelity is so high that it has been adopted by both Lockheed-Martin and CSC as the official development tool for the production of the first Open Architecture AN/SPY-1 RCCP version. TCE consists of a test harness and the tactical code. The test harness provides the tactical doctrine, environment, threat models, interceptor warhead debris model, and analysis tools. The tactical code includes the actual AN/SPY-1 tactical code modules for the Search Management, Radar Scheduling, Output Command, Radar Return, and Track Processing Modules along with input / output buffers.

TSC’s high fidelity simulation of the AN/SPQ-9B radar system, consists of a detection model and the local air tracker. The detection model is a full signal processor simulation including the effects of folded clutter and front end analog filtering. The Local Air Tracker models the multiple hypothesis tracker used by the AN/SPQ-9B to unfold Doppler and range ambiguities. The interface between the two components is regularly used to test model validity by running detection model outputs through actual AN/SPQ-9B hardware at Northrop Grumman Norden Systems in Melville, NY.

TSC also provides modeling and simulation support to the NSWCDD Theater Warfare Department for Ground-based Mid-Course Defense (GMD) program. TSC developed a simulation of the GMD system, the NMD Probability Analysis Tool (NPAT), to independently validate and verify the Boeing GMD LIDS in support of the accreditation of the GMD system requirements and design. NPAT is an object-oriented, open system design that enables plug and play of models of varying degrees of fidelity into the NPAT simulation.

TSC’s M&S efforts include treatments of propagation and clutter. Propagation affects both the detectability of targets (friend, foe, and neutral) and the measurement of their locations and kinematic states, which in turn, affects tracking performance of radars and EW sensors. Clutter also affects the detectability of targets and presents the added problem of false alarms from clutter. TSC developed a novel data compression algorithm under a US Navy SBIR program to accurately model the propagation effects.

TSC has considerable background and expertise in constructing IR/UV stimulators and simulators for both the US Air Force and the US Navy. IR targets, target arrays, and stimulators have been developed for the Air Force EW Evaluation Simulator (AFEWES) facility in Fort Worth, TX and the Naval Air Warfare Center (NAWC) China Lake, CA. In addition, TSC developed IRGEN, an IR signature modeling tool that converts a visible scene into an IR scene using commercial simulation database tools. IRGEN predicts the IR signatures of ground vehicles, ships, aircraft, cultural objects, and sky and terrestrial backgrounds.

EG&G has expertise in analyzing and evaluating complex electronic and ordnance systems using locally developed modeling and simulation software. EG&G developed a model titled Maximum Allowable Environment (MAE) Program used to identify the maximum electromagnetic environment an ordnance item can be safely exposed to based on the physical and electrical characteristics of the ordnance and its associated platform. EG&G has extensive experience in the design and programming of missile trajectory models given raw mathematical equations. These include Three Degree-of-Freedom (3-DOF) and Six Degree of Freedom (6-DOF) trajectory simulation models (SIXDS and SIXDM) of the TRIDENT II (D5) missile.

EG&G provides developmental and operational support for the Multi-warfare Analysis and Research System (MARS) simulator, and support exercises and experiments for both the Navy Area (endo-atmospheric) and NTW (exo-atmospheric) programs. EG&G employs the MARS simulation to analyze both Navy Area and NTW TBMD platforms and manage and support MARS exercises. EG&G supports the operation of several GMD software labs, including the Joint National Integration Center (JNIC) in Colorado Springs, Colorado; and the GMD Lab at NSWCDD. EG&G also provides programming, engineering and system support for analysis, design, and architecture development for the Navy’s Joint Simulation System (JSIMS), Joint Maritime Gaming System (JMGS) and Submarine Multi-Mission Team Trainer (SMMTT) programs.

Lakota has been providing domain expertise to support Digital System Resources, Inc. (DSR) efforts to associated with the US Navy’s Common Command and Decision (CC&D) and Common Network Interface (CNI) programs. These programs are laying the foundation for future combat system functionality that will be developed using open standards, COTS hardware and reusable warfighting components for use within a wide variety of systems. As part of this support, Lakota has performed the following tasks: developed a distributed real-time battlegroup simulation environment for testing new combat system functionality; developed a software architecture for migrating the Cooperative Engagement Processor (CEP) from the VME/VxWorks environment to a Symmetric Multiprocessor (SMP) workstation using the Solaris operating system; designed target identification, tracking and correlation algorithms for use within new combat system functionality; designed and developed a simulation to perform the data exchanges that occur in a Joint Tactical Information Distribution System (JTIDS) network; and developed a branched and stacked open architecture communications network responsible for providing CEC data to non-CEC equipped users.

SSA, under subcontracts GS-23F-0032L/A2S17B1277 and N00024-96-C-5166, has modeled multifunction radar time and energy utilization for the AN/SPY-1 family of radars. The results of recent activity are driving new changes to the Baseline 7.1 radar control computer program to increase system efficiency.
