Electronic Warfare

Contributing to the warfighter's success through EW techniques and equipment

Electronic warfare (EW) is increasingly important to the protection and success of the warfighter in today’s complex battlefield environment. EW provides access to the battle space (air, sea, land, space, and cyberspace); diminishes the enemy’s capability to attack; and ultimately, saves lives.

Due to the increasing use of electronics to support warfighting, EW applications are critical to deter, detect, prevent, and defeat threats such as missiles, radars, aircraft (manned and unmanned), maritime vessels, land threats, hostile space systems, and cyber threats.

Dynetics supports the design, development, and testing of EW techniques and equipment through work with the Intelligence Community, service labs, and operational elements.

Electronic Attack, Protect, and Support

EW uses the electromagnetic spectrum (EMS) or directed energy (DE) to control the EMS or attack the enemy. Dynetics develops concepts and conducts analyses of candidate EW techniques for each of the three EW components: electronic attack (EA), electronic protect (EP), and electronic warfare support (ES). And we provide EW operational and engineering expertise and direct support across the entire spectrum of EW missions.

Dynetics’ Contributions to EW

Using data analysis, reverse engineering, threat weapon system exploitation, and threat weapon system test and evaluation, Dynetics develops a comprehensive description of the threat weapon system. This description forms the foundation for the development of effective EW techniques and equipment.

Our threat descriptions are designed to accomplish the following goals:

  • provide a complete system definition
  • support US vulnerability assessments and countermeasure development
  • support tactics and simulator development
  • provide an authoritative basis for EA, EP, and ES system requirements
  • provide detailed waveform descriptions to support operational units

A complete threat description comprises numerous products, each with its own unique application to support design, development, and testing of EW equipment.

ITEAMS

Dynetics is a key participant in the revitalization of the all-source intelligence data analysis process which is addressing the need to define the capabilities of advanced threat weapon systems. 
Known as Integrated Technical Evaluation and Analysis of Multiple Sources (ITEAMS), this process assembles a group of Intelligence Community subject matter experts from around the country to assess the architecture, capabilities, and vulnerabilities of modern threat weapon systems. Dynetics is defining the performance of these threats that will drive specifications for subsequent development of simulators for these threat weapon systems.

Testing of EW Equipment

Dynetics’ high-fidelity models and simulations of threat weapon systems, including models of radars, jammers, seekers, and radar warning receivers, support all phases of EW equipment development from concept of operations, through design and development, to test and evaluation.

Dynetics’ high-fidelity real-time simulations of threat weapon systems are used in several hardware-in-the-loop (HWIL) test facilities throughout the US to test EW equipment under development or undergoing upgrades.

We design and fabricate special test equipment and instrumentation to characterize the performance of threat weapon systems. These models, simulations, and test equipment are used to:

  • characterize performance of threat weapon systems
  • reveal threat system vulnerabilities
  • provide realistic threat systems responses to support EA technique development
  • provide realistic jammer waveforms and models to support EP system development

Dynetics developed four integrated threat aircraft weapon system models to serve as intelligence baselines for the F22 aircraft combat simulation (ACS). This simulation contained several digital models including airborne intercept radar, identification friend-or-foe (IFF) system, radar warning receiver (RWR), missile launch detector (MLD), electronic attack system (EAS), fire control system (FCS), cockpit displays and controls, air-to-air radio frequency (RF) missiles, and air-to-air infrared (IR) missiles.

To characterize the performance of threat weapon systems and to support developmental testing of EW equipment, Dynetics develops special laboratory test equipment at several open-air test ranges in the US and overseas. This test equipment is used to reveal threat system vulnerabilities and to develop potential EW countermeasure techniques and tactics for further consideration.

TLS

To evaluate potential tactics and countermeasures related to Manportable Air Defense Systems (MANPADS), Dynetics developed the Extended Target Track-Loop-Simulator (TLS). The TLS is a real-time hardware-in-the-loop (HWIL) simulator designed to evaluate vulnerabilities of infrared (IR) homing reticle-based seekers.

The TLS simulates extended target IR scenes with conventional and directed energy countermeasures, seeker optics and detectors, and directly injects the detected scene into the actual threat seeker tracking loop ahead of the pre-amplifier. The scene content is controlled by user-selectable setup parameters, and motion of the scene with respect to the seeker is controlled by the output of the tracking and wing loops of the seeker.

Tactics and countermeasure combinations for a given aircraft and engagement scenario can be varied and analyzed to evaluate the missile effectiveness against potential tactics or countermeasure/tactic combinations.

Electronic Support (ES)

Through detailed signal analyses, Dynetics develops innovative threat radar signal representations for use in improving the performance of EW systems. We also develop predictions of IR, ultraviolet, and RF signatures to support development of algorithms to identify and track threat missiles.

Dynetics supports the development of NGES, the Next Generation Electronic Warfare Integrated Reprogramming Database (EWIRDB) System. NGES, an open architecture database for representing radar threat systems as models, significantly improves the dissemination of threat RF waveform descriptions. The NGES tools developed by Dynetics allow interactive analysis and visualization of threat RF waveforms and interface of these waveforms into RF simulators for testing of EW equipment.

Electronic Protect (EP)

Dynetics develops, implements, and evaluates EP techniques that cover the full spectrum of system components, as well as operational strategies for mitigating susceptibility to enemy EA. Our contributions in this area include design and evaluation of antenna specifications to achieve low angle sidelobes to mitigate sidelobe EA and clutter, EA-resistant waveform designs, and advanced signal and data processing techniques for EP support to address noise EA and jamming. 

Sustaining Obsolete Equipment

Dynetics’ system engineering and reverse engineering expertise addresses sustainment obsolescence issues of EW equipment such as the A5 filter/detector assembly of the AN/ALR-69 RWR. We developed a technical data package (TDP) that provides all information necessary to manufacture the assembly. This TDP will enable the government to replenish its spare parts inventory by procuring this item from any qualified manufacturer of these types of microwave components.

Support across the Entire Spectrum

Dynetics will continue to provide expertise and support across the entire spectrum of EW missions. Critical areas supported include the following:

  • improvised explosive device (IED) analysis
  • integrated air defense systems (IADS) analysis
  • survivability and countermeasure effectiveness analysis
  • EW modeling and simulation
  • EW vulnerability testing and analysis operational test support
  • EW training
  • EW capabilities-based assessments

Dynetics’ long-standing support to the US Intelligence Community and ongoing work with service labs and operational forces ensure new EW concepts, techniques, and equipment meet the challenges of current and future threats to our military.
