Directed Infrared Countermeasures (DIRCM) Principles Training Course – Hands-on
In this 2-day Directed Infrared Countermeasures (DIRCM) Principles Training, the design of phase- and amplitude-sampling DRFM architectures are presented along with their problems and solutions. Narrowband and wideband designs are compared. Calculation of the spurious signals is presented and design strategies for advanced DRFM decoys for counter-targeting, counter-terminal applications are emphasized. Methods to synthesize multiple, structured false-targets against high range resolution profiling radars (ISAR, SAR) are presented. Derivation of false-target phase and gain coefficients are discussed including those for the required clutter models. Digital circuit design issues e.g., quantization errors, overflow, dynamic range are addressed. Methods used by adversaries to discriminate the DRFM false-targets from actual targets are offered leading to further DRFM design considerations. Lessons learned from recent EW flight tests are emphasized.
This course is intended primarily for radar, EW engineers and scientists interested in the design of digital RF memories and signal processing algorithms for electronic attack. Attendees should have a good knowledge of radar systems and signal processing. Many example problems are worked out to demonstrate the concepts and further the understanding of the material being presented.
