Fused MAD/ELFE Detector for MMMDS

Dynamics Technology, Inc. (DTI) will develop and validate a combined MAD/ELFE detector for airborne submarine search and tracking to support the Multi-Mode Magnetic Detection System (MMMDS). The new detector will fully integrate with the onboard noisemitigation processor.DTI proposes to base the detector development and fusion on ELFDET, a prototype DTI processor developed under separate contract. ELFDET contains, or can accommodate, all the necessary components (noise reduction, MAD, ELFE) for a combined detector but hasyet to generalized. In this contract DTI will focus upon further development of the Rao detector for ELFE signatures and its relationship to noise and MAD detection. The detector utilizes ELFE basis functions in a matched field type detection algorithm.The basis function approach will be generalized to take better advantage of the signature characteristics and to include a complex envelope. After the ELFE detector has been much improved, DTI will focus upon optimally redesigning the order of processingand the effect of each processing step upon those following.The improvements to ELFDET will form the foundation for the Phase 2 tasks to fully fuse and test the MAD and ELFE detectors with the noise mitigation algorithms. The results of the proposed effort will significantly enhance the Navy's ability to upgrade the existing airborne MAD system. MAD has been identified as a necessary technology for the Navy's shallow water ASW program (SWALAS). The primary customers foradvanced MAD system are the U.S. Navy and our allies. DTI is teamed with sensor and platform partners for commercial production of the next generation system.
