EW Environmental Generation Engineering - Part 2

Electronic Warfare RF Stimulus Architectural Fundamentals and Tradeoffs

Simulating an electromagnetic environment relevant for testing EW devices is a challenging engineering problem that is full of trade-offs and design complexity. This multi-part presentation series will walk the audience through common engineering challenges and design considerations to help the test engineer be more knowledgeable about the complexities of creating an EW environment. The next generation of EW devices and platforms brings new difficulties: modern threats become faster, more agile, and more complex. The testing challenges for our friendly devices scale accordingly with these modern threat enhancements. This presentation series is meant to frame those problems and allow the test engineer to consider multiple possible solutions, understand the engineering design trade-offs of each one, and to more intelligently solve these environmental generation test challenges in the future.

This presentation will cover the fundamental concepts of EW signal generation from a bottom-up approach. The discussion will cover the conversion chain from the digital backend of EW scenario generation to the analog RF output. Topics covered will include: pulse descriptor word fundamentals, fundamentals of RF emitter bandwidth, frequency, and level considerations, the multiple RF port system architectures, the alignment of multiple RF ports in time, level, and phase, and the phase locking of a multi-port RF system. The audience will leave with a deeper understanding of the trade-offs between a variety of architectural details when evaluating an EW signal generation system.

In this webinar, you will learn how to/ more about:

• Fundamentals of EW signal generation
• The conversion chain from the digital backend to the analog RF output
• Pulse descriptor words fundamentals
• Multiple RF port systems architectures
