2 Overview  EW SIL  Virtual environment for HWIL  EO SIL  Equipment  Applications  Signature Generation  Simulation Motion  False Alarm Environments  Requirements on Sources and Source Capability LED DMD  Future Plans

3 EW Systems Integration Laboratory  HWITL/HITL virtual environment (EW SIL)  EO SIL – MAWS, LWR  RF Systems  Virtual MANPADS, RPG  Virtual Cockpit Demonstrated real-time integration with CECOM HITL  Software models

4 EO Systems Integration Laboratory Facilities  Instrumented Threat Warning Systems  47/54/57/60  VVR-1  Stimulator Instrumentation (UV)  Baringa, Hydra, Mallina, Real-time sources (UV LED Insertion under contract)  HiFi Signature Generation  Sensor Motion Control  Real-time shot truthing  Control Software  Simulation Definition  Simulation Execution Automatic Manual Networked  Analysis

5 Sensor/System Evaluation  Sensor Characterisation  Sensitivity, FOV, fault verification  Laboratory replay of trials  Pd determination  Engagement time-lines  Virtual trials  Utilising high fidelity signature generation  Stochastic False Alarm Comparison  Currently unable to replicate:  Atmospheric Scatter  Multiple targets (~ 100) in repeatable way  Atmospheric Scintillation (yet)

6 High Fidelity Signature Generation  Parameterisation of Off-axis Scattering Intensity Calculation (OSIC) + Occlusion Model  Inputs  Sensor Parameters  Threat, Sensor positions and orientations  Threat emissions and Atmospheric Conditions  Output  Photon Intensity distribution  Photon distributions generated off-line into 6-D look-up table  Coupled with appropriate fly-out model  Generates scene of distributed photons for each time-step of fly-out model Better than real-time demonstrated (provided intensity not too great)  Currently only direct and near-axis scattered component implemented in EO SIL

7 Shot Truthing  Stimulator Shot Truthing  Core to qualification of trial replay capability  Instrumentation of actual field radiometers Immediate determination of deviation from intended shot  Includes elementary image truthing Object counting for FAR analysis Potential motion truthing

8 Lateral Motion

9 Laboratory False Alarm Environments  Requirements  Multiple sources  Varying radiometric signal characteristics Attack/sustain/decay + modulation  Independent motion  Stochastic Evaluation  Reflected tinsel/disco-ball  Arbitrary Stochastic Evaluation  UV LED
