Experiment, Learn, And Plan For The Next-Gen SIGINT And EW Mission

Threat Representative Environment (TReX) is a better way to experiment, train, and plan next generation signals intelligence (SIGINT) & electronic warfare (EW) operations.

What Is TReX?

TReX is a software and COTS hardware-based signal simulator. It is an easy to setup hardware and software suite that enables users to conduct true testing and evaluation of EW systems and techniques, anytime and anywhere.


  • Helps prepare signals intelligence (SIGINT) and electronic warfare (EW) operations against cyber-electromagnetic activities (CEMA) in spectrum-intensive environments with over-the-air, high-fidelity software-defined emulation of complex threat emitters
  • Enables operators to conduct testing and evaluation of advanced electronic attack (EA) defeat techniques
  • Leverages extensive signal libraries and expands to support new signals and hardware capabilities
  • Simulates multi-domain operation (MDO)-representatives across electromagnetic environments (EME) for training with scalable, high-fidelity threat realism

A Better Way To Experiment

TReX hardware can be easily set up in a lab, outdoor range, or deployed environment. It acts as a “victim” system that enables users to transmit and receive high-fidelity representations of many commercial and non-commercial threat emitters, and test new SIGINT and EW techniques against their waveforms. Users may observe and validate the effects of applied SIGINT and EW systems and techniques on the simulated victim radios via the TREX software controller.


A Better Way To Learn

Trainers can create simulated SIGINT and EW engagements within the TReX software and measure the effects on enemy devices by monitoring bit-error-rate (BER), signal-to-noise ratio (SNR), and throughput. Simulated threat waveforms can be quickly modified and/or saved as new signals to equip operators with everchanging threat signals.

A Better Way To Plan

TReX can be used to practice CONOPs in a network simulated environment. Multiple TReX devices can be remotely controlled and communicate with a single, C2 software application. Real-time and post-session data can be used to plot threat effectiveness and improve planning for future strategies by mission command. Users can create long duration and/or repeatable scenarios for quantified testing in the lab or field. TReX has the capability to mimic specific threat radio waveforms including but not limited to:

  • Fast, frequency hopping tactical radios
  • Fixed-frequency tactical radios
  • Unmanned Aircraft Systems (UAS) and Remote-Controlled Model Aircrafts (RCMA)
  • GNSS, DVB-S, DVB-S2, and DVB-T signals
  • TDMA/CDMA bulk transmitters
  • Non-commercial adversary modems
  • Comms modulations: FSK, BPSK, BPSK-DSSS, OFDM, and QAM
  • Pulse emitters and radar signals

TReX software is flexible and compatible with a wide range of COTS devices (e.g. USRP X310, E210), and provides custom hardware configurations to meet mission needs. The TREX system is versatile enough to be fitted with small, lab environment components up to large, MIL-SPEC outdoor units with high powered amplification. TReX’s web-based software leverages in-house digital signal processing (DSP) to outfit operators with generic or specific custom signals of interest (SOIs).
