All you need to know about Nigeria’s Skyguard Fire-Control Radar System.

The Italian built Skyguard firecontrol radar system is a search, acquisition and target designation anti-aircraft fire control radar system for airborne targets flying at medium, low and very low altitudes. Its equipped with two radar for search and track. It also uses a digital computer instead of the earlier analog equipment. The search radar is a fully coherent pulse Doppler system. It utilizes a common transmitter in tandem with the acquisition radar.

Operating in the I/J band and attaining a peak power of 200 W, it offers fast frequency change and fast PRF change facilities with a choice of pulses. A cosecant-squared antenna with integrated IFF uses a horizontal beamwidth of 1.7 degrees and a 55 degree beam in elevation

A cosecant-squared antenna with integrated IFF uses a horizontal beamwidth of 1.7 degrees and a 55 degree beam in elevation features of the search radar include automatic target alarm, automatic lock-on and computer controlled symbol markers on the PPI. The tracking radar is also a fully coherent monopulse antenna with a 24 degree beamwidth.

Signal processing circuits provide 80-m acquisition gates around the tracking gate (all having Doppler filters), while the total acquisition range is 1140m. The display is an R-trace, displayed on the TV monitor for tracking supervision and ECM monitoring.

Target acquisition and tracking is automatic and includes memory tracking and automatic alarm facilities. Special features include fast target exchange and automatic noise jammer tracking. The acquisition radar operates in the K-band. Skyguard is deployed either with AA gun systems or AA missile systems and is commonly used with the Aspide or Sparrow missile.

 

Operational Characteristics. Skyguard was developed to act as either an autonomous anti-aircraft fire control radar aboard a vehicle, a separate trailer-mounted unit or as an element within an air defense system. The equipment is designed for short-range acquisition of targets down to and including ground level.

Particular emphasis has been placed on the ability to detect hovering low-level helicopters. The Nigerian Army has a battery of 16 ROLAND SHORAD (Short Range Anti-Aircraft Defense System) and Type 90 35mm anti-aircraft cannon controlled by a Skyguard radar system for airfield defense.

 

The Skyward is connected to radar guided anti-aircraft cannons like the Chinese Type 90 and the Russian ZS 24-2 AA gun.

The NAF deploys these radars, they are installed in mostly in airbases and used to monitor the altitudes flown by aircraft performing penetration and training missions.
