Complex definitions:


An actor describe any platform with embedded equipments (emitters, receiver, jammer, …).

For example fighter1 and fighter2 can be two actors based on the same plaftform ( i.e. F15 Fighter) each having their own embedded equipments.

Actor is synonym to Player.


A uniquely identified simulated radar emitter. An emitter can have the following types:

  • CW: a continuous wave transmission modulated or not.

  • Simple: a pulse emitter having a constant and repetitive set of pa­rameters.

  • Complex: an emitter having a variable and complex set of parame­ters, such as stagger, pulse dwells, ….


Equipment is a list of materials embedded on a platform.

Equipment includes:

  • Generator or receiver description (radar emitter, jammer, receiver)

  • Antenna positioner description in case of mechanical antennas modelling.

  • One or several antennas (mechanically mounted on an antenna positioner, or electronically scanned).


A simulation mode, in which some actors movements and antenna scanning are controlled from the System-Under-Test during simulation execution.


Represents the position in space (X, Y and Z axis), orientation, velocity and acceleration vectors of an actor.


A platform is the physical description of any actor (for example F16, airport tower, or ELINT station are platforms).

A platform can be identified by:

  • Id (unique id of the platform)

  • Name

  • RCS

  • Picture (optional, quasi real representation, 3D object)

  • Description

  • Symbol (graphical representation)

  • Kinematics (position in space, velocity)

  • Equipments list


Synonym to Actor.


Scenario means description of actors with embedded equipments, how they move in space, how they use there equipments, and more generally all the parameters that makes a simulation unique (ground surface description, weather conditions, …). All this parameters are stored in a scenario file that can be recalled at any time to reproduce the simulation.


A simulation mode, in which the movement information of the System­Under-Test is either pre-programmed or controlled with a joystick, but not affected by the status of the System-Under-Test.

System-Under- Test

The actual Radar or EW system connected to the Radar Target/Jamming Generator or the Signal Environment Simulator. The RF outputs of the Sys­tem are connected to the receiver channel of the System-Under-Test.


An object in the scenario, which creates radar echoes.
