6 DASS Sensor Fusion Modern Platforms Have Integrated DASS/Sensors = Sensor Fusion Typical Sensors/System Include Radar ESM/RWR LWR MAW Active ECM Chaff Flares

7 Modern Platform Sensors & Countermeasures Components Radar

8 Sensors & Countermeasures Components Up to 40 GHz 3-5 and 8-11 micron I/J-Band Sensors RWR MAW LWR Radar DASS COMPUTER A/C Systems Data Bus ECM Chaff Flares DIRCM Countermeasures DASS computer processes raw data from the sensors to make its decisions

9 Integrated Systems Primary Processing Functions Fuse sensor data to enhance target recognition effectiveness Correlate sensor data to enable high accuracy targeting Provide coordinated countermeasures to maximise platform survivability Sensor integrated testing is essential in order to verify these functions

10 Requirements for Multi-Sensor Testing Provide coherent stimuli to all sensors Provide stimuli at the same time Generate stimuli from a common scenario = tactical engagement modelling Repeatable test scenarios Multi-spectral ( DC to Light )

11 Integrated System Testing Requirements To/from data analysis systems RF Stim RWR IR Stim MAW Central Control Computer Common Scenario Generation Control of Stimulators Linked to Data Analysis Systems Laser Stim Target Gen LWR Radar

12 Common Scenario Generation Requirements Real-time execution 6 DOF modelling for platforms Accurate propagation models Terrain models and terrain obscuration Easy-to-programme Easy-to-edit Repeatable

13 Common Scenario Generator Radar threat simulator already provides the complex scenario modelling and is a good starting point Enhance the platform models and data bases to include radar, MAW, LWR, etc Expand interfaces to include control of additional sensors/sub-systems

14 Platform Dynamics Modelling Requirements X, Y, Z, roll, pitch, yaw movements 3-D platforms Platform targeting Inter-related platform movements Platforms with weapon systems (missile launch, etc) Platforms with chaff, flares, etc

15 Increase Platform Asset Capabilities Definition

16 Add Various Stimulator Control into Scenario Control UV and IR stimulators by adding threats into scenario data bases and interface controls Control radar target generator (RTG) using platforms as target returns

17 Integrated T & E Process Radar Threat Simulator provides the necessary scenario models, propagation models, dynamics, etc Within scenario, UV/IR and laser threats (stimulators) are added and controlled by the Radar Threat Simulator Platforms in the RTG become the targets to radars using radar target generator

18 RWR Testing Requirements Generate user required threats to very high fidelity 6 DOF platform movements Model DF interface (4 ports, 8 ports, etc AOA, Phase, DTOA, etc) 500 MHz to 40 GHz frequency coverage 100 s of emitters/platforms Trigger chaff deployment if required

19 Radar Testing Requirements Generate targets that match the RWR platforms 3D target returns JEM lines Rotor blade modulation Target RCS fluctuations Connect to radar at RF and generate targets in correct range, Az, El, bins

20 MAW Testing Requirements Generate realistic missile UV/IR signatures and profiles Multi-spectral stimulation (3-5 and 8-11 microns) Missile dynamics in simulation to correlate with radar tracks Trigger flare deployment if required

21 LWR Testing Requirements Generate laser-guided threats (beam riders, range finders, target generators) Multi-spectral in 1 micron spectrum area

22 Realisation of Integrated Test System Scenario generation Emitters Platforms IR Profiles IR signatures Laser Designator profiles Target RCS JEM Lines Chaff models THREAT STIMULATOR IR/UV STIMULATOR LASER STIMULATOR DRFM RADAR TARGET GENERATOR Control Control Control RWR MAW LWR RADAR

23 Connections to the Systems Under Test Direct inject/direct coupled Provides full 360 o Az and +/- 90 o El Fully stimulates sensors through their performance range Most expensive solution Radiated through the air One angle only- no DF information Less hardware than direct inject Flexible: multi-site usage Limited range

24 Anechoic Chamber Radiation Methodology

25 Some Australian Projects with Direct Inject Integrated Testing Air87 has integrated test system RF Stimulator IR Stimulator Laser Simulator Echidna has integrated test system RF Stimulator IR Stimulator

26 The Future for Integrated Testing Integrated test and evaluation systems will become essential in their usage as integrated DASS systems are deployed IFF, Comms, Navigation elements can be added and will be necessary These systems will be fully automated and will reduce test times considerably

27 The Future for Integrated Testing Many countries will encompass an indigenous & independent testing capability for preservation of critical data and knowledge Systems like JSF are around the corner and Integrated DASS testing is needed

28 Summary and Conclusions Integrated testing is essential in modern DASS systems By using a radar threat stimulator as the basic controller and scenario generator, integrated testing is already here now and in service Considerable time and $$ will be saved through the use of this type of multi-sensor, multi-spectral testing Deployed systems will be tested to a much more rigorous level through integrated testing and Customer 1 ( the user ) will have a higher performance and reliable DASS
