Phase IV Expertise

Modeling, Simulation, and Algorithm Development

Phase IV Systems has over 15 years of experience in sensor and system simulation modeling in both the BMDS and tactical arenas as well as decades of experience in various weapon system algorithm development efforts. When combined with our parent company, Technology Services Corporation, our combined experience provides considerable depth and breadth in the BMDS area.

Phase IV developed the real-time multi-threaded radar interface emulator of the THAAD radar, the Radar Interface Emulator (RIE) for the BM/C3I Integration and Test Environment (BSITE) as well as the radar model used for the THAAD system coverage performance analysis (THAAD Block 6 CDR: FOOTSAT/Medium-Fidelity-End-To-End Radar Model (METER)). These high performance models written in Ada and C provide critical interface and integrated sensor performance analysis (Autonomous Search, Cued Search, Enhanced RV Detection Methods, Detection, Track, Discrimination). Additionally, variants of these models (JEDI: Joint Environment Driver Interface) provide inter system functional performance for the US government at the System Engineering Directorate at Redstone Arsenal in Huntsville, AL.

The scope of the modeling and simulation does not stop at sensors. Phase IV has developed and integrated various high performance models and simulations as described below:

Threat Trajectory Simulation:  The THAAD Threat Generator (TTG) is a high performance 6 DOF trajectory generation tool, which rivals the performance of other tools such as Dice or STAMP. This C++ trajectory generator is capable of quickly (~10 ms or less) generating entire threat state trajectories and Euler angles for virtually any configured threat. This procedure call driven program can seamlessly integrate into any simulation to provide 6-state data on any number of associated threat objects or pieces, from any combination of launch and impact points. Unlike DICE and Stamp, which require MATLAB, have no command line interface and run at a slow pace, the TTG is a robust, configurable simulation, perfectly suited for real-time and mass-raid studies on any type of ballistic threat (separating or non-separating: SRBM, MRBM, IRBM, or ICBM). The TTG is currently integrated into the THAAD Defense Design Planner (DDP-TFCC) and the LMMS Integrated Missile Defense Test Bed (IMDT).

Real-Time RCS Generation:  The RCS generator is a near real time high fidelity model for the simulation of aspect angle dependent radar cross section (RCS) parameters. Leveraging off improvements in high fidelity RCS computation algorithms, the RCS generator provides radar sensor simulations with virtually instant aspect angle dependent RCS parameters. The RCS generator inputs are comparable to the legacy XPATCH RCS program, (3-DOF Threat Models, Transmit Frequency, PW, Chirp, Polarization, etc…), but can be called via procedure calls from any simulation or integrated model framework. This simulation flexibility allows for the real-time sensor evaluation of emerging threats or system evaluation in specific high profile scenarios. Unlike more well known programs which have no viable real-time program interface or operate as selected frequency ranges, the RCS generator can be utilized over the entire RF band, with multiple sensors simultaneously. The RCS generator is currently being integrated into the LMMS IMDT, for integrated system performance between THAAD, Aegis, SBX, FBX-T, and the BMDS Sensor Network.

Algorithm Development and Analysis:  Phase IV systems has an extensive staff of experienced doctorate and master level engineers to either develop, review or evaluate algorithms for a wide variety of technical areas.
