VREX Architecture


The FishEye Software Virtual Receiver/EXciter (VREX) is modularized in the same fashion as a typical front end radar.

Starting at the right hand side of the green box in the figure below, VREX includes an Interface Binder that is configured to match the Radar Interconnection Diagram (ICD) to connect to the back-end. The VREX has a standard radar interface that connects to the Interface Binder. This allows the internal VREX interfaces to be common to all radar implementations.

The VREX is configured to produce any variety of waveform which is then sent to a Transmitter simulation which in turn drives the Target and Environment simulations to produce an expected target return. Alternatively, External Simulators can be employed to generate targets or to modulate the environment as desired.

The simulated Receiver and Digital Module accept the target return simulations and process them to generate I&Q data that can be sent back to the back-end as shown.

To provide representative equipment behaviors such as maintenance faults and status reporting, the VREX includes an Equipment Simulator that uses configured scenarios to drive the reporting.

A configured Observer Scenario drives models that use this observer viewpoint to modulate the response to targets.

Configuration files drive the VREX simulation, each of which are text-based and easily modified to fit the particular need of the project.

Underneath VREX is the FishEye Real Time Platform (RTTK). This data capture tool allows data collection, analysis and display of internal information within the simulation as needed.
