Title: Eung Gi Paek: Innovator in Time Transfer Technologies
Introduction
Eung Gi Paek is a prominent inventor based in Germantown, MD (US), known for his groundbreaking work in time transfer technologies. With a total of 10 patents to his name, Paek has made significant contributions to the field, particularly in satellite-free time transfer systems.
Latest Patents
One of his latest inventions is the "High-performance time transfer using time reversal (T3R)." This innovative concept allows for satellite-free time transfer over long distances, achieving an impressive accuracy of approximately 200 ns rms. The invention proposes methods to enhance performance to below 10 ns rms, surpassing the capabilities of current differential GPS systems. The new approach utilizes the Vernier concept, leveraging the unique p-independence property of T3R, regardless of carrier frequencies. Additionally, Paek has introduced a histogram method to filter extraneous data, ensuring high accuracy, and a technique to extend the timing range of T3R by eliminating ambiguity. He also addresses signal blockage issues caused by transmit/receive window mismatches and proposes solutions for ionospheric challenges, enabling 24-7 operation in adverse conditions.
Another notable invention is the "Distributed time-reversal mirror array (DTRMA)." This system consists of multiple independent, sparsely distributed time reversal mirrors (TRMs). Each TRM is equipped with an antenna and a transceiver for transmitting and receiving signals. The DTRMA operates autonomously, utilizing time-reversal's self-focusing feature to sharply focus beams on targets, minimizing distortion from external sources.
