The AN/MPN-25, a highly mobile, compact Airport Surveillance Radar (ASR) / Secondary Surveillance Radar (SSR) / Precision Approach Radar (PAR) System, provides highly accurate detection of the airspace around an airport or air base. Simultaneous ASR/SSR and PAR operations from the single sensor develop accurate radar data of both types. Versatile, multimode digital color displays and full communications in a tactical Operations Shelter support all controller mission requirements. The ASR covers 30 nautical miles (nmi) and altitudes up to 8,000 feet. The SSR range is 100 nmi. The PAR range is 20 nmi with an azimuth coverage of 30 degrees and elevation coverage of 8 degrees.
Superior Operational and Technical Performance
The AN/MPN-25 rolls on and off a C-130 transport for quick emplacement; it is fast and easy to install with automatic set-up; and its human-machine interface is full color and arranged to reduce fatigue in the high-stress controller environment. The AN/MPN-25 achieves runway changes in less than a minute - much faster than any competing system. The AN/MPN-25 achieves excellent target detection and tracking even in severe environments such as heavy rain. High stability and advanced digital processing featuring Moving Target Detection (MTD) and extensive mapping ensure adaptation to the changing environment.
Versatile High-Resolution Multimode Displays
The AN/MPN-25 Operations Shelter includes three universal color displays that controllers individually assign ASR or PAR mode based on traffic needs. The FAA-certified ASR display format covers the air situation. The PAR display provides 3-D landing information in a state-of-the-art, digital Az-El format. This patented display adds an innovative “bullseye” to give the controller a pilot’s view of the approach.
Focused Advanced Technology
The AN/MPN-25 achieves its outstanding capabilities through integration of advanced technology into a cohesive user-friendly system. GaAs Transmit/Receive Modules populate two active apertures for the azimuth and elevation antennas, thereby eliminating the single point transmitter failure. Commercial off-the-shelf (COTS) processors and power supplies ensure low-cost and high reliability.
Non-Stop Operation and Low Support Costs
The AN/MPN-25 modular, open architecture; solid-state design; and air cooling achieve availability and reliability superior to any other radar-based landing system. Incorporated redundancies increase fail-soft protection.
Very low support costs are inherent in the AN/MPN-25 through highly reliable solid-state technology, minimized unique Line Replaceable Units (LRUs), and extensive built-in test. Reduced deployed maintenance costs are a direct result of designed-in fail-safe/fail-soft operation requiring only scheduled periodic maintenance. Maintenance is further enhanced through remotely monitoring all system functions via telephone lines.
