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

2  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. Networked EW for the ADF

3 1. Define the problem 2. Develop analysis plan 3. Define Measures 4. Produce results 5. Analyse results 6. Prove the results 7. Communicate & document results OA Methodology

4 Analysis Tool Force Level EW Synthetic Environment FLEWSE Architecture

5 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 Analysis Tool - FLEWSE

6 OA Module Structure STAGE/CSMI Executes individual simulation runs CONTROL (Stage Batch Runner) Controls a sequence of simulation runs Relational Database (MySQL) Simulation events Logged to database POST PROCESSING TOOL Creates reports AnalysisData Extraction Reports Selected data queried from database for sequence of runs Analysis Tool - FLEWSE

7 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 How does it work: Hypothetical example

8 1. Define the problem 2. Develop analysis plan 3. Define Measures 4. Produce results 5. Analyse results 6. Prove the results 7. Document results Evaluation Process

9 1. Define the problem 2. Develop analysis plan 3. Define Measures 4. Produce results 5. Analyse results 6. Prove the results 7. Document results Evaluation Process Liaise with RAAF and identify issue(s) requiring analysis: -What is the threat? -What is the effectiveness of current ADGE systems in detecting, locating and identifying threat systems, and how a GBESM may help Select a scenario as a context for the evaluation through elaboration of the RAAF and Adversary’s: -Objectives -ORBAT -CONOPS -Doctrine

10 1. Define the problem 2. Develop analysis plan 3. Define Measures 4. Produce results 5. Analyse results 6. Prove the results 7. Document results Evaluation Process Define alternative options for analysis that will discriminate the issues under consideration: - effectiveness of ADGE systems - GBESM technologies Develop vignettes appropriate for studying each alternative in the context of the scenario

11 1. Define the problem 2. Develop analysis plan 3. Define Measures 4. Produce results 5. Analyse results 6. Prove the results 7. Document results Evaluation Process Sensor Measures: Detection/ID range Time to detect/ID Number of entities detected Location error at first detect Location error at engagement Sensor settings Engagement Measures: Number of threats destroyed Number of RAAF units destroyed Loss Exchange Ratio
