Electronic Warfare Simulator (EWSIM)

EWSIM is a physics-based Military Combat Environment, many-on-many simulation and threat environment with a large order of battle, ideally suited for both stand-alone mission rehearsal and distributed mission simulation. Using EWSIM, you can quickly and easily extend your distributed simulation framework to include EWSIM generated semi-autonomous forces (SAF). EWSIM supports the Distributed Interactive Simulation (DIS) architecture including simulation management, entity state, fire, detonate and emissions PDUs. EWSIM was designed to put the power of simulation in the user's and instructor's hands and reduce the need for contractor support. EWSIM provides users with the ability to build effective and realistic scenarios, easily make dynamic inputs into the simulated Battlespace in real-time, modify threat data, and analyze simulated operations. EWSIM has teamed with some of the best-of-breed simulation experts in the industry to ensure EWSIM provides the best quality image generation, threat performance, weapons parameters and characteristics, flyable flight models, and graphical user interfaces, making EWSIM cost-effective, diverse, flexible and adaptable, yet easy to use.

Robust Threat Environment and Battlespace Management

EWSIM can simulate a fully Integrated Air Defense System (IADS) comprised of Early Warning, Acquisition, Height Finding and Target Tracking radar. Each sensor is modeled down to the pulse level to include the dynamic generation of high-fidelity emitter audio. EWSIM simulates air-to-air and surface-to-air missile fly-outs and air-to-ground weapons and ballistics. Instructors can make real-time, dynamic inputs into the scenario by adding or moving threats, including both surface-to-air missile (SAM) systems and aircraft equipped with airborne radar and air-to-air missiles. The EWSIM user interface makes managing the scenario simple. EWSIM allows users to add and remove entities, reload weapons, employ weapons, input environmental factors, direct electronic attack and perform a variety of analysis functions without any scenario interruption.

Train Anywhere

EWSIM is built upon a mature Geographic Information System (GIS) core. That means your virtual Battlespace is the entire world! That's important because it means EWSIM can be used for operational mission rehearsal and not just for a couple of 'canned' training scenarios. EWSIM supports dozens of industry standard raster and vector formats. Raster formats include NGA standard Compressed Arc Digitized Raster Graphics (CADRG), Compressed Imagery Base (CIB), LizardTech MrSID (.sid), Enhanced Compressed Wavelet (.ecw), GeoTiff and JPEG 2000. Vector formats include ArcView Shape (SHP) files, Google Keyhole Markup Language (.kml), and NGA's Vector Product Format (VPF).

Live Virtual Constructive (LVC) Mission Rehearsal and Simulation

In addition to live, in-flight GPS feeds, EWSIM is also an advanced, stand-alone constructive mission rehearsal simulation. A true mission-level simulation, EWSIM can simulate many-on-many in real-time, including both red and blue aircraft, early warning (EW), height-finding (HF), acquisition (ACQ) and target-tracking (TT) radar, radio communications, surface ships and ground vehicles.

Simulating an IADS

During mission simulation, the EW, HF, ACQ and TT radar sites in EWSIM are linked together to form an Integrated Air Defense System (IADS). The IADS can be imported from FalconView (4.0 or newer) or created in EWSIM -- you can even import a real electronic order of battle (EOB) in PCI format. The ability to realistically simulate an IADS is a clear differentiator between EWSIM and simulations which rely on scripting or simplistic rules to trigger radar activity. In EWSIM, a complex algorithm is executed for each sensor in the battlespace. Does the sensor have line-of-sight to the target? Is the target obscured by stand-off jamming? Has the sensor burned through the jamming, if present? Has chaff bloomed in the resolution cell? Is the radar already tracking its maximum number of targets? Is the target beyond the sensor's maximum range as determined by the Radar Range equation, taking into account the sensor's frequency and target's radar cross section, and not just a simplistic 'max range' number? Is the site operating autonomously, or is it linked into the IADS? Can the site still communicate with its parent or child sites? Is the target already assigned to another target tracking site? Which target is the most attractive? EWSIM answers every single one of these questions, for every single sensor in the battlespace, many times per second.

Missile Flyouts and Ballistic Flyouts

EWSIM uses a physics-based aerodynamic model and limited guidance model for missile fly-outs. Missile aerodynamics are derived from weapon thrust, drag, and weight. Weapon thrust is calculated by the motor's mass flow rate and specific impulse. Drag is calculated by the missile's drag reference area, coefficient of drag (subsonic and supersonic), speed, and atmospheric conditions at the flight altitude. Missile weight is reduced as propellant is burned. The missile flight profile is based on a four-stage approach that includes a free fall time, booster stage, sustained stage, and glide stage. The guidance model will shape the missile's flight path to a loft, direct intercept, or dive profile while maintaining the target within the seeker's gimbal limits in pitch.

EWSIM also uses a physics-based aerodynamic model for ballistic fly-outs. The ballistic flight path is determined from drag and weight. Drag is calculated by the weapon's drag reference area, coefficient of drag (subsonic and supersonic), speed, and atmospheric conditions at the flight altitude. The weapon's pitch is matched to its flight path angle. The ballistic model / equations are flexible enough for bombs, artillery, and bullets.

Fully Integrated and Articulated Avionics and Combat Equipment

Since EWSIM is purposefully designed as a data-driven application, the end user can add or edit their own threat data, even down to the pulse level for generating emitter audio. EWSIM has a wide variety of Sensors and displays and can be expanded to suit your needs.
