1. Evaluating the Benefit of Networked EW Systems
Greg Chalmers and Keith Mason

2. Networked EW for the ADF
The focus of ADF EW procurements for many years has been on EW self protection as a last resort in missile defence.
The 2009 Defence White Paper has put increased emphasis on networked operations, including EW operations.
For example, the sharing of EW sensed information across force elements for situational awareness
Evaluating the capability benefit of EW for networked operations is a very different activity to that of EW for platform self protection.
DSTO has developed a methodology and analysis tool to evaluate the benefit of EW systems to support force level ADF operations.
This methodology and tool provides a means of comparing EW technologies, force-mix options, and CONOPS to measure mission success.

Analysis Tool - FLEWSE
Modeling Infrastructure
STAGE: COTS reconfigurable simulation framework for developing tactical synthetic environments. Includes simple platform, EW systems, sensor & weapons models
CSMI (Combined Sensor Modeling Infrastructure): In-house developed EW sensor/effector models to enable computation of EW system performance
Limitations:
- Effects based modeling
- Does not model detail of tactical engagements

7. How does it work: Hypothetical example
Awareness of inbound air threats currently relies on radar surveillance. Could an EW sensor help?
Ground Based ESM (GBESM) offers:
Earlier warning than ground based radar
Emitter type, platform type, intent
Use OA methodology and tool to compare:
Realistic ADF missions with current ADF capabilities
Same missions with additional GBESM capability
