7 Time – Energy Budget Allocation of EM energy to specific MFR functions
Face 1 occupation 100% Horizon search Short range search Limited volume search Confirmation Cued Search Target designation Air track Weapon (target) track Missile track Missile Acquisition Midcourse guidance Terminal illumination 0% time

8 MFR Management Issues Allocation of the Time Energy Budget (TEB) : the EM energy available and the related time for surveillance, tracking and weapon control functions is only limited available  functions have to be prioritised Operational restrictions like Rules of Engagement or Emission Control plans have to be taken in to account Each function has to be optimised with respect to a specific task and the environmental conditions Many degrees of Freedom: Complex Human Machine Interface

9 Sensor Management Operator Decisions :
when to use which sensor and sensor function for picture compilation or weapon control while taking into account: Emission Control plans Rules of Engagement how to set a sensor for optimal results with respect to the mission objectives and meteorological/ geographical conditions

10 Sensor Management Context Diagram
Operator Common Operational Picture Mission Related Information Sensor Management System Sensor Sensor Settings C2 System Sensor Observations

11 Command and Control (I)
Picture Compilation Processes Observe Orient Sensor Operational Picture Decide Act Sensor Management Processes

12 Basic OP object attributes:
OP Object Properties Basic OP object attributes: state vector (position, velocity, acceleration) type/class identity …… related uncertainties

13 Compilation of Virtual Objects:
Prior Information Compilation of Virtual Objects: Expected state vector (position, velocity, acceleration, direction, ….) type/class identity …… Structured use of Intelligence

14 Command and Control (II)
Picture Compilation Detect Track Classify Identify Fuse Determine Threat Recognise Intent Estimate Risk Analyse Behaviour Mine Data Plans Mission Knowledge Operational Picture System Knowledge Env. Knowledge Plan Evaluate Construct Task (Monitor) Select Resource Control Resource Mission Management Resource Management Sensor Weapon C4I Platform Crew

16 Sensor Management Three Sensor Management Stages :
Analyse the contents of the Operational Picture w.r.t. uncertainty, missing information  Construct Task Determine which of the available sensors is the most appropriate  Select Sensor Optimise the selected sensor for this task  Control Sensor

17 Required Knowledge Knowledge about the System Knowledge about the
Environment Knowledge about the Target (Mission)

18 Sensor Performance Models
Knowledge about the system Cone of Silence Knowledge about the Target No detection due to multipath Knowledge about the Environment No detection due to Radar horizon

19 Sensor Performance Analysis Performance Optimisation
Model Utilisation Sensor Performance Analysis Performance Optimisation Sensor Selection Mechanism

20 Performance Visualisation

22 Function Selection and Budget Allocation

23 Summary Sensor Management has to be integrated in C2
The Operational Picture is the basis of Sensor Management Not Functions, but Tasks are prioritised Validated Performance Models required Use of Environmental Information Autonomous Adaptive Sensor Deployment is feasible
