"Vehicle Protection Jammer" is a system for detecting and silencing control radio signals for undermining mine devices.
"Improvised Explosive Device" (in translation - self-made explosive devices) has recently become the main source of the loss of personnel of peacekeeping units and the forces of "restoring democracy" in the Middle East. The main purpose of “Improvised Explosive Device” is to be installed on or near roads as mine devices that are undermined while driving at the place of installation of vehicles. Of the wide range of methods used to detonate improvised mine devices, the most common of these is the detonation using a remote radio-controlled fuse.
The developer of this active system is Cassidian, a division of EADS. The equipment on which this active type of Vehicle Protection Jammer will be installed, according to the developers, will be provided with reliable protection from homemade mine devices with radio remote control.
The principle of "Vehicle Protection Jammer" is based on listening to the radio in order to search for radio signals that can be used as a remote activator of the mine device fuse. When a signal is detected, a vehicle operating in the immediate vicinity, on which the active vehicle type Vehicle Protection Jammer is installed, instantly (one microsecond) begins to transmit chaotic signals at the detected frequency. This action completely distorts the original signal at the detected frequency, which in practice should lead to blocking the activation of the mine device’s charge. Today, different types of active suppression systems are used in service, basically, they have a certain drawback - they constantly emit a strong radio signal in a wide frequency range. Such systems have rather large overall characteristics and require a powerful source of energy for their constant work.
"Vehicle Protection Jammer" uses the power of its transmitter only at the moment when the receiver detects a certain signal. The transmitter turns on and emits a chaotic signal only at the detected frequency. Such an organization of the work of the system allowed the use of a very small source of energy for work, for example, an ordinary generator installed on the equipment used can cope with such a task. The overall characteristics of the Vehicle Protection Jammer will allow the installation of this mine protection even in an ordinary passenger car - it will easily fit in its trunk.
