Innovative Aircraft Landing Aid Transmission Technology

In Phase II of this SBIR, DTI will design, build, and test three complete transmitter assemblies for the AN/SPN-41 Landing Aid Radar. The first, an Engineering Development Model (EDM) will be designed to the requirements defined with the Navy in Phase II, and provided to the Navy for testing and assessment. Two preproduction units, will be designed for MIL qualification and Navy testing in AZ-EL configuration. Each transmitter will mount to existing equipment and behave as the current transmitter, but with improved reliability and higher quality RF output. The new transmitter will use either the L3 or CPI magnetron. Internally it will be organized like the existing transmitter, with two main circuit assemblies, a power supply and a high voltage modulator. During Phase II (and the proposed Phase II Option), DTI will move the transmitter as far towards qualification and production readiness as SBIR funding will allow. At the conclusion of the Phase II effort, the upgraded AN/SPN-41 transmitter will be ready to complete qualification testing and move into production under a Phase III SBIR effort.
