SEG Capabilities
Systems Engineering
SEG supports Navy and Missile Defense Agency programs in a broad spectrum of systems engineering that includes system requirements definition, specification development, data reduction and analysis, performance analysis, trade studies, and modeling and simulation. SEG's M&S capability includes a sophisticated end-to end combat system performance model comprised of a federation of sensor, weapon control, interceptor, and threat models. SEG has been a key participant in the development of a new multi-channel Coherent Data Collection System (CDCS) and an extensive set of data analysis tools to analyze the performance of the A/N SPY-1 Radar.
Threat & Missile Systems Engineering
SEG is working with the Missile Defense Agency and the U. S. Navy to provide detailed understanding and engineering characterization of threat ballistic missiles for use in ballistic missile defense system design and evaluation. SEG's areas of expertise include: high fidelity threat missile modeling and simulation, foreign weapon research and development, and foreign missile systems engineering, design and performance analysis. Our staff works closely with the Intelligence Community at the engineering level to ensure the use and timely availability of intelligence information. We have pioneered the concept of fully correlated, time-synchronized flight dynamics and RF/IR signature data to support high fidelity simulation and real-time hardware-in-the-loop (HWIL) applications. These characterizations represent the full target complex and are used for weapon system requirements development, shipboard tactical databases, trade studies, design, evaluation and test.
Radar Systems Engineering
SEG has developed and interfaced a versatile suite of tools for radar design and analysis that includes Receiver Transmitter (R/T), FPGA, and a PC cluster to emulate parallel processing on Power-PC based DSPs. These tools are designed for efficient and cost-effective transitions between the computer lab and the HW using in situ software and firmware development as part of the analysis and design process. Consequently, the SEG Radar Division is capable of providing true life-cycle support for our products from algorithm development to HW implementation given processor and bus usage constraints. The entire simulation suite is stimulated by a high-fidelity scene generator that includes coherent sea and land clutter with rigorous platform motion, target motion, and INS models that permit detailed scene generation for robust analysis and design of challenging modes such as SAR, GMTI, ISAR, and BMD HRR waveforms. An object-oriented approach to radar simulation permits rapid prototyping of disparate radars from airborne maritime surveillance and imaging to Navy multi-mission radars such as the AN/SPY-1. Distributed processing using a built-in socket layer class minimizes execution speed of each high-fidelity radar simulation and permits interfacing of the federation of models such as BMD end-to-end simulation (sensors, interceptors, and threat server).
Software Development
SEG has significant experience in the development of real time embedded systems with emphasis on Radar. This includes algorithm design, real time software, human-machine-interfaces, and system integration and test. We have developed innovative algorithms, techniques, and simulation environments in areas of flight dynamics, CAD, RF and IR signature modeling, and visualization. We have developed software both in API and executable formats in multiple programming languages, supporting several computer platforms. SEG exercises state-of-the-art software development procedures encompassing requirements definition, software architecture design, implementation, verification and validation and user documentation. Recent programs include the development of trackers for Radar, IFF and AIS sensors; net-centric sensor fusion processors; radar imaging software for ISAR, STRIPMAP and SPOTSAR; high bandwidth air-ground RF data links; and data visualization tools.
