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

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.

OA Methodology 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

Force Level EW Synthetic Environment Analysis Tool Force Level EW Synthetic Environment FLEWSE Architecture

Modeling Infrastructure 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

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

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
