====== About ====== Dr. Pavel Kovar is an Associate Professor of Radio Engineering and Radio Navigation at the Czech Technical University in Prague. His father, Vratislav, was an aviation designer. /*who developed radio navigation and communication instruments. In 1969, he patented "Variable frequency divider circuit wiring," which enabled the design of a fully synthesized VHF Air Com transceiver, LUN 3524.*/ Since childhood, he has been preparing for a career as an electronics developer. His father introduced him to mathematics, physics, and electronics. They developed various electronic devices. After graduating with a Ph.D., he worked for three years as a designer of aviation communication systems. He modernized the communication system for the Czech Army's MIG-21 fighters. In 2000, he returned to the university as a teacher due to the poor state of the industry and a health condition. His strong background in industry and deep theoretical knowledge allow him to connect theory with practice when preparing students or solving technical and scientific problems.
