1 PRI Prediction Enhances EW Training By Scott McDonald & Ken McRitchie Ottawa, Ontario, Canada Visit us at MC Countermeasure Inc.

2 19-Feb-20022Visit us at Overview Training vs Operational ECM Need for Prediction PRED Features PRED Performance Summary

3 19-Feb-20023Visit us at DRFM DRFM-based ECM originally developed for fully coherent applications Constant PRI makes up-range false targets easy Would like to do same with non-coherent/coherent on receive radars

4 19-Feb-20024Visit us at Training Application RAN/CF Programs DRFM-based ECM

5 19-Feb-20025Visit us at Operational vs Training Mil-spec Protect platform Configuration control Optimized by threat Highly integrated, compact size Benign environment Non-interference Highly programmable Generate a variety of ECM effects Must replicate current and future generation ECM

6 19-Feb-20026Visit us at Constant PRI

7 19-Feb-20027Visit us at Staggered PRI

8 19-Feb-20028Visit us at Radar Characteristics Surveillance, search, acquisition, TTR, TI Constant, dwell shift, modulated or staggered PRI patterns –Multi-element/position –Sliding –Sinusoidal 2 us < PRI < 14 ms

9 19-Feb-20029Visit us at Isolation Many antennas compete for little space in most EW Training installations –Leads to insufficient isolation to transmit and receive simultaneously –Precludes cover pulse –Situation corrected with PRI prediction

10 19-Feb Visit us at Features Fast “learning” –No UDF Prediction < 250 ns > 128 positions Adaptive Acquisition Fade mode TG Enhancements

11 19-Feb Visit us at Block Diagram

12 19-Feb Visit us at Integration with TG

13 19-Feb Visit us at Optional FT Generator

14 19-Feb Visit us at Performance 1

15 19-Feb Visit us at Performance Minimum PRI (us) Stagger Pattern Length Known Radar Parameters Specification Measured 15/8/01

16 19-Feb Visit us at Summary PRI prediction is necessary to effectively use a DRFM-based system in a modern EW training application –Prediction circuitry is not standard MC Countermeasures has developed a line of predictors that can be easily interfaced to existing training systems –Integrated with existing TG –Provide additional TG capability –Work around insufficient antenna isolation

17 19-Feb Visit us at Acknowledgements The authors would like to acknowledge the contributions of Dan Grise and Remi Gauvin who did much of the hardware and software implementation.
