Electronic Warfare and Countermeasures
Countermeasures, Threat Analysis
and Environment Generation
What is Electronic Warfare?
Electronic warfare (EW) involves denying an enemy the use of the electromagnetic spectrum (EMS) or gathering intelligence of an enemy’s intended actions or capabilities through analysis of transmitted electromagnetic (EM) signals.
Electronic Warfare uses electromagnetic spectrum for offense, attack and mission support. From air, land and sea, it can target forces, communication, radar and other assets (military and civilian).
Threat and Electronic Countermeasure (ECM) analysis
Tektronix is a leader in delivering integrated measurement tools that help military and government personnel accurately recreate the physical and electromagnetic environment exposed during field operations and electronic warfare. Real Time Spectrum Analyzer (RTSA) technology can be used to capture, visualize and trigger on threats and electronic countermeasure responses.
Tektronix Real Time Spectrum Analyzer systems are used to quickly discover and characterize:
- True RF signature of a signal of interest (SOI) in spectrum, frequency/amplitude/phase versus time domain
- Analyze the physical characteristics of signals of interest even if they are hidden within or are under other signals
- Validate threats and countermeasure response during operation testing
Accurately Simulate Environments While Measuring ECM Techniques
At Tektronix, we are the leader in delivering integrated measurement tools that help military and government personnel accurately recreate the physical and electromagnetic environment exposed during field operations and electronic warfare.
Today, the dynamic congestion contained within the Electromagnetic Spectrum from other emitters, jammers, and interferes demands higher fidelity instruments to accurately simulate the environments represented in the field to ensure electronic protection systems are fully tested out, so our military forces can detect realistic threats and stay out of harm’s way.
Techniques for Validating Electronic Countermeasures
This webinar examines approaches for ECM performance validation. A few examples of what you will learn: discover the true RF Signature of Threat stimuli and verify ECM Techniques using real-time spectrum analysis, and how to verify coordinated techniques in both the time domain and frequency domain simultaneously.
Advanced Radar Analysis
Rapid advances in radar technology means you're developing and manufacturing highly specialized and innovative electronic products to detect radar signals. You need to reduce uncertainty and increase confidence during the design process. This application note digs into the tools you need to handle modern radar applications.
The full-motion DPX spectrum's Live RF display shows signals never seen before, giving users instant insight and greatly accelerating discovery and diagnosis. Learn more about DPX with this primer.
Accurately replicate physical and electromagnetic environmental effects
Performance in the lab is never as true as performing in the field. That’s why, in verifying key performance parameters during system development testing and technique development in the lab or chamber, requires introducing atmospheric and electromagnetic effects to the waveform scenario generation. Tektronix has high fidelity arbitrary waveform generators coupled with powerful software enabling multipath generation, high pulse dense environments and attenuation control for rain, fog and other electromagnetic effects.
Tek has durable instruments that replicate the following with precision:
- Physical positional effects
- Physical atmospheric effects (rain, fog, dust storms)
- Electromagnetic effects (clutter, multipath)
Multidomain visibility for validating ECM techniques real-time
Development test events and chamber time can be costly. Capturing data right the first time is essential. Real-time situational awareness allows for validation of countermeasure techniques without any interruption to the test event, verifying technique transitions in both time and frequency domains requires high resolution captures.
All if this can be done with precision tools enabled by RSA Spectrum Analyzers. With Tek’s form factors RSAs, you can also:
- Recreate lifelike radio signals as precisely as possible
- Build complex signal environments
