Barak 8 is a very important project for the Indian Armed forces,it will provide India the much required medium/long range air defence/point defence to protect her strategic land base assets and well to project the navy as a blue water capable, the Kolkata class is designed to include the MF-STAR radar component and would carry 32 to 64 Barak 8’s, the radar seeker used in the missile and the MF-STAR AESA Radar are important technologies that India is benefiting from the collaboration.
India is contribution with the rocket system, the dual pulse smokeless solid rocket motor is also a vital component that gives the missile the needed thrust to engage the target.
•RAFAEL supplies the Barak-8 interceptor missile, which remains vertically launched.
•The battle management, command, control,
communication and intelligence center (BMC4I) is produced by the MBT Division of IAI’s Missiles, Systems, and Space Group; it offers both stand alone operation for a single fire unit, and joint task force coordination (JTC).
•IAI ELTA Systems Ltd. supplies the Land-Based Multi-Function Surveillance, Track & Guidance Radar (LB-MF-STAR), a rotating S-band digital Active Electronic Steering Array (AESA) Radar System that can deliver an accurate, high quality arena situation picture, and extract low radar cross section targets like stealthy cruise missiles, even in the toughest environmental conditions. The naval MF-STAR is expected to be part of Israel’s next-generation missile frigates.
As per IEEE standards BARAK-8 (Long Range Surface to Air Missile <LRSAM> / Medium Range Surface To Air Missile <MRSAM>) uses multi band seekers
HF : 3 to 30 MHz
VHF : 30 to 300 MHz
UHF : 300 MHz to 1 GHz
L : 1 to 2 GHz
S : 2 to 4 GHz
C : 4 to 8 GHz
X : 8 to 12 GHz
Ku : 12 to 18 GHz
K : 18 to 27 GHz
Ka : 26.5 to 40 GHz
V : 40 to 75 GHz
W : 75 to 110 GHz
mm : 110 to 300 GHz
What are the disadvantages and advantages of different frequencies ?
• Gives Higher range, lower accuracy, lower power consumption, negligible influence by weather conditions. Lower frequencies are mainly used for long range transmit and broadcast.
1) ITU ELF (Frequency range: 3 to 30 Hz; Wavelength range: 100,000 to 10,000 km) used for communication between land and submerged submarines far away
2) IEEE L Band (Frequency range: 1 to 2 GHz; Wavelength range: 3to 1.5 dm) used for air volume search aboard ships like Thales LW-08 on INS Kolkata
•It gives Lower range, higher accuracy, higher power consumption, highly influenced by weather conditions. Higher frequencies are mainly used for short range pin point locating.
1) IEEE Ku Band (Frequency range: 12-18 GHz; Wavelength range: 2.5 to 1.67 cm) used for target acquisition for missiles like Astra
2) IEEE mmW (Frequency range: 30 to 300 GHz; Wavelength range: 1cm to 1mm) used for target acquisition for missiles like HELINA
