CICERO, N.Y. — The U.S. Patent and Trademark Office has recently issued SRC, Inc. a patent for “Discrete Time Adaptive Notch Filter,” a process that allows for the selective filtering of complex signal components in radar systems.
The patent develops an adaptive digital filter designed to efficiently remove specific types of unwanted interference, while minimizing the loss of signals useful to a radar, SRC said in a July 22 announcement. A distinctive feature is the filter’s ability to automatically track interference frequency using minimal firmware resources, enhancing efficiency, and efficacy without sacrificing performance, the company noted.
The inventors for this patent are John Dougherty, chief systems engineer, and Andrew Nadeau, staff systems engineer, both employees of SRC. Dougherty is also named on seven additional patents, the company said.
“By rethinking traditional approaches, SRC engineers continue to develop reliable, resilient solutions,” Kevin Hair, president and CEO of SRC, contended in the announcement. “This innovation underscores our commitment to redefining possible and delivering advanced technology that keeps America and its allies safe and strong.”
SRC, a nonprofit research and development company, says it combines information, science, technology, and ingenuity to solve “impossible” problems in the areas of defense, environment, and intelligence. Founded in 1957, SRC today has more than 1,400 employees, including engineers, scientists, and other professionals.
