Radar Jamming System, GRJ-87KU

General Description
GRJ-87KU is a light weight, portable radar jamming system which radiate interfering signals toward enemy’s ground surveillance radars working in KU frequency band. This system is used to reduce the Maximum detection range and quality of detection of ground surveillance radars. GRJ-87KUcan be installed on a tripod and its erection time is very short.It is equipped with a visual LCD display that shows jamming modes and emitting frequency of the jammer.
Features:

• Capable of connecting to a RWR system
• Operatable in manual and automatic modes
• Ability of jamming all types of ground surveillanceradars.
• bility to transmit three types of signal (CW,
• Sweep and Impulse) and two types of noise (wide
• Band and Spot)
• Built in test ( BIT ) capability
• Light weight and man probable

Accessories:

• Additional battery
• Battery charger
• Tripod
• Compass
• Knapsack
