What is the MSSR 2000? HENSOLDT’s IFF and Secondary Surveillance Radar
Every aircraft in controlled airspace must answer a single question: who are you? The MSSR 2000 (Monopulse Secondary Surveillance Radar) is HENSOLDT’s answer — a NATO Mode 5-compliant IFF and secondary surveillance radar deployed at military radar stations and civilian air traffic control facilities worldwide.

How It Works
The MSSR 2000 operates differently from primary radars. Rather than detecting reflected energy from its own transmissions, it interrogates transponders carried by aircraft. The radar sends a coded interrogation; the transponder replies with identity, altitude, and other data. The monopulse measurement technique achieves precise angular measurement from a single interrogation pulse — significantly more accurate than conventional rotating-beam SSR systems.
NATO Mode 5 compliance ensures the system can positively identify allied aircraft during coalition operations, close air support missions, and joint air defense scenarios — preventing fratricide in complex battlespace environments.
