5 Technology Considerations for Electronic Warfare/SIGINT Communication Systems

As the variety and complexity of communication systems in the modern RF battlefield increases, the equipment and tools used to analyze the signals must keep pace. Warfare in the 21st century requires communications systems be able to use spectrum such as radio and radar signals to protect and communicate. There are five critical considerations for these systems:


  • Technology that can cover wide frequency ranges
  • Ability to process high bandwidths in real time
  • Synchronization scalable across multiple channels
  • Support for flexible development tools
  • Technology platform that can integrate across systems and other platforms

In addition, these same signals can be used to disrupt or deny signals used by adversaries. From the sea to the air to the ground, NI’s advanced measurement technology provides the capabilities needed in the 21st-century information battlefield.


NI software defined radios (SDRs) give you unprecedented hardware and software integration to accelerate your innovation for electronic warfare and SIGINT applications by covering wide frequency ranges, processing high bandwidths of data in real-time, providing synchronization scalable across multiple channels, and supporting flexible development tools.    


At NI, we’ve served the aerospace and defense industry for decades with disruptive, PXI-based instrumentation and application software that reduces the overall cost and risk associated with the design, prototype, test, and support of your EW and SIGINT solutions.


More specifically, our graphical programming environment—also known as LabVIEW—combined with a PXI Vector Signal Transceiver (VST) can help you perform the real-time radar target simulation needed to keep up with the changes you’re facing.



In this video, one VST is used to both generate and receive the radar signal, while the other is used to emulate the environment in which the radar is operating through channel emulation. Multiple radio cross section models are available for the radar channels, as well as multiple path types such as liner, swirling, and clutter.
