Abstract: In an aircraft for range training of pilots in electronic warfare countermeasures, a device for simulating a threat environment on the cockpit instrumentation. The device comprises an image simulator controlling the threat azimuth indicator, and a control code receiver. The control code is transmitted via the up-link communication system from the air combat manuevering range ground station to the airborne instrumentation subsystems. The control code is recognized by the receiver and applied to the image simulator. The entire device is installed in place of the present threat signal countermeasure receiver and signal processor.
