RF Applied to Electromagnetic Warfare

RF applied to Electromagnetic Warfare training course is a 4-day training program that provides a deep understanding of the RF principles applied Electromagnetic Warfare (EW) systems. Electronic Warfare (EW) represents the ability to use the electromagnetic spectrum and variety of different signals including radio, microwave, EO/IR (electro Optical/Infrared) and radar to sense, protect, and communicate. Electromagnetic Warfare (EW) can also be used to deny adversaries the ability to either disrupt or use these signals.

EW is divided into three (3) major areas: Electronic Attack, Electronic Support and Electronic Protection.

Through lectures, discussions and hands-on lab using spectrum analyzer and logic analyzer participants will learn about RF principles, electromagnetic waves, propagation, and antenna principles applied to radar systems and operation, radar-enabled weapons, jamming and interference principles, Electronic Attack, disrupt, deny, degrade, destroy, or deceive, Electronic Protection, preventing a receiver from being jammed or deceived and Electronic Support, sensing of the electromagnetic spectrum, EW RF threat modeling and simulation,  and EW concepts and application in TDLs such as Link 16, TTNT, Link 22, VMF and more. Tonex instructors will bring spectrum and logic analyzers, oscilloscopes, antennas and more.

In the air, on land, and at sea, advanced technologies to control the electromagnetic spectrum, and disruptive technologies to outpace adversary threats are key topics covered in this course: Naval Electronic Warfare, Surface Electronic Warfare, Ground Electronic Warfare, Airborne Electronic Warfare, Cyber Electronic Warfare, functional capabilities that provide real-time situational awareness, enabling principles to intercept signals that identify both imminent and potential threats. Adding layers to defense, countermeasure technologies use EW to protect against missile attacks. Tonex course build knowledge and skills in EW and protection, platform development and integration, that includes electronic warfare systems, electronic support measure (ESM), phased array radars, radar warning receiver (RWR), electronic intelligence, communications intelligence, and anti-jam GPS products.

The key to success lies not only in the capability of the systems, but also cross-domain technologies and integration of those systems across platforms to offer a complete picture of the battle space and unimpeded use of the electromagnetic spectrum for the warfighter.
