ATI's IFF & SSR Beacon Identification Systems course

Share |


    Technical Training Short On Site Course Quote

      This fast moving three-day course is designed for managers, engineers and technicians who need an understanding of the basics of IFF/SSR radar beacon technology and systems. The principles of the various IFF/SSR systems are presented. The system design tradeoffs are discussed in the context of the different target identification and air traffic control mission requirements. This course will provide the ability to understand and communicate with IFF/SSR engineers and project personnel.


      Dr. Patrick W. Johnson is a former Navy Commander and founder and former President of American Electronics. He is now Sr. VP for R&D at ZAI, Inc. He received a BS from the U.S. Naval Academy, an MSEE from the Naval Postgraduate School in Monterey, California, and his PhD from Queens University in Kingston, Ontario, Canada. While in the Navy, he was the OPNAV sponsor for shipboard radar and target identification systems. At Amelex, he was the Principal Investigator for a continuing series of radar and IFF/ID programs and projects for the Army, Navy, Air Force, FAA, NASA and DARPA.
