Professor of electrical engineering

Richard Kozick '86 is conducting important research in addition to his classroom teaching. He is working on several signal processing projects with colleagues at the Army Research Laboratory in Adelphi, Md.

One project involves sensor networks, in which sensors make measurements in their environment and then communicate with each other with wireless radio links. Kozick is focusing on a particular sensor network in which microphones and other sensors are distributed over a field for detecting, localizing, tracking, and classifying moving vehicles, aircraft, and personnel.

Another project is related to radar, which is used in military and civilian applications to locate aircrafts in the sky and ships in the ocean. In radar, a radio signal is emitted through an antenna, and then the reflections from objects are received and processed. "Typically, several radar emitters are deployed over a geographic region," says Kozick. "If we are in an aircraft, and we notice that a radar has turned on (because we can measure its radio signal), can we determine which specific radar emitter sent the signal?" This is the problem of specific emitter identification (SEI), and Kozick is studying fundamental bounds and algorithms for SEI.

Kozick also is a dedicated teacher. In 1999, he received a Presidential Award for Teaching Excellence from Bucknell.
