Overview of Secondary Surveillance Radar (SSR) and Identification Friend/Foe (IFF) Systems - Part I - Virtual Lecture - CEU/PDH Available

Share

The lecture is composed of two one-hour parts.

In Part I a general overview of SSR/IFF is presented which includes a review of terms and definitions. From there, a historical timeline of SSR/IFF is summarized beginning with early implementations and ending with modern day systems. Then system architectures are reviewed starting with block diagrams and the challenges of scanning airspace. System-level features discussed include sidelobe suppression, antenna dwell time, azimuth determination and RF link budgets. In addition, the trade-offs between 2-channel and 3-channel systems are reviewed.

Biography:

Frank Messina is the Chief Engineer of the SSR and IFF products for Telephonics. Frank has 50 years of experience in the design, development, and fielding of innovative IFF and SSR products for Military and Civil use. Frank is the lead IFF Interrogator Systems Engineer for the world’s fleet of AWACS aircraft, US Navy P8-A Multi-Mission Aircraft (MMA), US Navy MH-60R aircraft, Canadian Maritime Patrol Aircraft (CP140), Canadian Maritime Helicopter (MHP), Canadian Frigate Upgrade, USMC G/ATOR, USAF D-RAPCON, Mode 5 Operational Autonomous Surveillance (M5 OAS), SAAB Giraffe Mobile Platforms and other ground, shipboard and airborne based products at Telephonics.

Earlier in his career, Frank was the lead engineer for the FAA Common Digitizer 2 (CD-2) SSR Beacon Extractor System. Frank was also instrumental in adding full Mode S interrogator capability to the NATO AWACS, which represents the first military IFF interrogator system to integrate the high-priority AEW Military IFF Modes with Mode S. He was also the IFF team leader for the design and development of the AN/APS-147 and AN/APS-153 IFF interrogator system – the first integrated and tightly-coupled Multi-Mode Radar and IFF interrogator fusion system. More recently, Frank lead the design and development of the AN/UPR-4(V) Passive Detection and Reporting System (PDRS) and Small Form Factor SFF-44 All-Mode Active and Passive IFF system.
