IFF Target Surveillance
and Acquisition System
IFF target surveillance
and acquisition system
Features
• Stand-alone IFF system
capable of providing real-time
IFF data over an Ethernet
interface.
• Comprised of an IFF
interrogator unit, IFF
antenna/rotator unit, and a
Windows-based PC providing
operator interface, PPI type
display, and Ethernet
interface.
The IFF Target Surveillance and Acquisition
System is a secondary surveillance radar and
display, providing aircraft location for range
safety as well as target acquisition. The antenna
can be mounted on a fixed mast or a
telescoping mast for mobile systems. The
compact digital interrogator is a rack-mounted,
solid state design with a monopulse transmitter
which provides an improved azimuth
accuracy over conventional systems. The
stand-alone design, including processor and
display, can interface to an existing tracking
system via standard serial link or Ethernet.
Target Display and Acquisition
• 1,000 targets per scan, 60 in-beam
targets
• Range accuracy and resolution of 378
feet
• Range greater than 100 miles
• Azimuth accuracy greater than 0.3
degrees
• PPI display over map
• Point and click target acquisition via
mouse or touch screen
• Serial target distribution to slave unit
Antenna/Rotator
• Can be mounted on a building top, fixed
mast, or on a telescoping mast for
mobile systems
• Two-speed Rotator: 15 RPM/30 RPM
•Vertically Polarized Antenna
Digital Interrogator
• Transmit: 1030 MHz +/- 0.2 Hz
• Receive: 1090 MHz +/- 0.5 MHz
• Modes 1, 2, 3 and C
• Monopulse TX for improved azimuth
accuracy

Typical System Configuration
Antenna and Rotator
The IFF antenna design complements the features and performance
capabilities of the interrogator’s transmitter and receiver. Sum and
Difference R.F. signal inputs provide antenna beam sharpening and
interrogation side lobe suppression for clutter reduction.
The antenna rotator is a weather-tight aluminum casting with stainless
steel hardware for harsh environments. The modular design allows for
rapid maintenance with minimum down time. A two speed motor
rotates the antenna providing data updates at either a 2 or 4 second
rate.
Interrogator
The Digital Interrogator transmits 2 KW minimum at 1030 ±0.2 MHz
and receives the transponder reply at 1090 ±0.5MHz. Four Selective
Identification Feature (SIF) modes are provided including Modes 1,2,3
and C interrogation pulse groups. Measurement of the round-trip time
determines the range to the replying target, while the boresight of the
interrogator antenna determines the azimuth direction. Typical range
accuracy is 378 feet with transponder delay time dominating overall
error.
IFF Processor
Digital data from the interrogator is transmitted to the IFF processor via
an Ethernet connection. The processor displays all targets detected by
the interrogator on a PPI scope over a map of the region and allows the
operator to select any target for radar acquisition. The acquisition data
is passed on in the proper format to the slave processor.
