Engineering the complete path from signal to usable data

Wideband systems often need more than a collection of standard components. Bandwidth, timing, interfaces, signal integrity, processing and deployment conditions must work together as one system.

WRS brings together RF design, high-speed digitisation, firmware, digital signal processing and systems integration to develop solutions around the requirements of each application.

About WRS

From RF capture
to digital insight

WRS works across the signal path, connecting RF acquisition, high-speed digitisation, timing, digital processing and data transport into a system designed for the wider mission.

Meet the Engineering Team

From technical requirement to supported system

  • Understand the requirement
    Define the signal, bandwidth, interfaces, environment and operational outcome.
  • Design the architecture
    Select or develop the RF, digitisation, timing, processing and transport components.
  • Develop and integrate
    Create the required hardware, firmware, software and system interfaces.
  • Test and validate
    Confirm system performance against the agreed technical requirements.
  • Deliver and support
    Provide the agreed documentation, commissioning, handover and ongoing technical assistance.
