Tactical Environment Assets

• Threats are air based
• Defended assets land based
• Asset attributes
• Size
• Geometry
• Asset priority

6
Sensors Effectors

• Sensors
• Track management
• Sensor and system tracks
• Hostility and type classification
• Measurable attributes
• Derived attributes

• Effectors
• Efficiency of effector
• WS and tracking sensor
• SSHP compute Pkill
• Assignment to threats

7
Threats of the system

• Threat movement in 3 dimensions
• Approach and attack techniques
• Interested in the VSHORAD ranges, i.e. attack
  techniques
• Divided into phases and stages

Deterministic Models

• Time-to-DA
• Shortest Orthogonal Distance
• Bearing
• Course

Project Status and Future Work

• TE Status
• Established theoretical background (4 years)
• Flagging Deterministic models implemented
• Working on Probability-based model subcomponents
• Data from TFDC OTB
• WA Status
• Working on theoretical background (2 years)
• Greedy WA and AP solutions implemented
• Working on all inclusive WA solution for
  benchmark
• Testing and Evaluation Status
• Started testing and TE models integrated
• Integration with the VGD (collaboration with
  DPSS)
• Growing Knowledgebase
• New masters student 2008 OIL
• Collaboration with IMT (work sessions)
• TEWA on higher levels (JAD) (RRS DPSS)
• Future implementations such as Task Force
  Assignment (SAP)
