The Israeli company TAMAR Explosives is introducing at Milipol 2009 the X-test range of explosive simulants, products specifically designed for training and testing of homeland security personnel. The X-test products realistically simulate the actual explosives they represent, in appearance, texture, odor, and density. It can be used for the training of EOD technicians and security inspectors, performing searches for explosive devices in passenger baggage.

They also represent similar chemical properties, such as effective atomic number (Zeff) computed tomography (CT number) to effectively represent the explosive material to advanced detection systems, such as millimeter wave and X-ray diffraction sensors. The company has also developed a range of improvised explosive devices training devices in which its explosives simulants are used, along with simulants of detonators, detonation cords, and a variety of initiation devices. Explosive vests, pipe bombs and other items – all inert – complete the assortment, allowing high fidelity train of security agents for high threat environments.

Being inert materials, such simulants enable trainees, instructors and inspectors to handle explosive training devices with relative safety, allowing trainees to get a feel of the actual explosives and IEDs, and also to train in detection via hand search or a variety of detection technologies. X-Test materials are used for the training of security agents performing manual checks aimed at detecting explosive materials, assisting agents in becoming familiar with the visual and tactile properties of various explosive materials and easily recognize them during the course of their work. Other uses are in the instruction of operators of detection systems such as X-ray and EDS, searching for explosives concealed in baggage and other personal belongings. The operators learn to distinguish the concealed simulants by detecting their images on their screens, even when hidden among other items. Such materials are also used in exercises carried out by regulators and airport authorities as well, to preserve the operation of the security setup at a constantly high state of alertness. These “red team” exercises also comprise a fundamental component of airports’ quality assurance program. Simulants can also be used for the training of dogs (K-9), taught to identify and spot explosive materials.

Cellphones and other wireless communications devices are providing terrorists an effective means of control. By separating the device preparation and placement from the actual activation, IEDs can be planted in different locations and be activated by remote command, in response to the target’s behavior – such as speed of movement, specific target vulnerability, local situation (vis-à-vis nearby civilians) or when a specific VIP is being targeted in a convoy.

As improvised explosive devices proliferated throughout the world, adversary operating techniques have also evolved, utilizing advanced triggering devices, enabling perpetrators to activate these explosive devices with devastating timing and accuracy, to overmatch passive and active means of protection such as ballistic armoring and evasive maneuvers.

To counter such remote-controlled devices (RCIED), electronic countermeasures IED defeat solutions are employed, including jamming, pre-activation and neutralization techniques. Originally known as ‘bomb jammers’ these devices were utilized by EOD/ bomb disposal teams, to deny an adversary to trigger a device under inspection by the EOD technician. These jammers are also used by first responders when arriving at terror scenes, in effort to deny the activation of secondary explosive charges planted at the site, aimed against the rescue teams.

The IED jammer effectively cuts off radio communications from the triggering transmitter to the device attached to the bomb, thus temporarily preventing bomb detonation while the jammer is in effective range.

At Milipol 2009, two Israeli companies – Netline and SESP are displaying advanced high-power jammers, among them devices designed for EOD and VIP applications.

An Insight into the IED

While jamming temporarily eliminates the threat of IED, the device remains highly dangerous until it is deactivated and eliminated. EOD teams tasked with this dangerous mission utilize robotic systems to inspect the suspicious devices and deactivate it by disrupting or eliminating the activation mechanism. While sophisticated equipment is available for visual inspection of the devices, looking through the devices, by X-ray or computer tomography is still a complex task handled by professionals.

Safely Training to Deal with IEDs

Another aspect of handling IEDs is the training of EOD, and security inspectors performing searches for such devices in passenger baggage.

Each member of the Netline’s C-Guard Very High Power IED jammers consists of multiple high-power transmitting devices, operating on different frequency bands, protecting personnel, vehicles and installations against complex threats, employing multiple threats operating over a wide area and broad frequency spectrum. To extend Radio Controlled Improvised Explosive Device (RCIED) protection, provided by the vehicular jammer to dismounted teams, Netline developed the C-Guard manpack. This system is designed as a lightweight, backpack system, to be operated by ground troops under risk of encountering remote controlled improvised explosive devices, including combat engineers, dismounted patrols etc. The battery powered system is blanketing a given area to prevent radio receivers from achieving RF signal for detonation of remote controlled explosive weapons. The system can be configured to cover VHF, UHF, cellphones and wireless devices, satellite phones etc.

To support bomb disposal units, a portable, battery-powered IED Jamming-device, such as the Netline TXP ECM can be employed. The system is housed in a trolley-style pelican case can be configured to operate on nearby AC main power or from an integral battery. These devices can be deployed to locations where the anti-IED vehicle has no access. Blocking multiple frequency bands in one case, the system covers a wide spectrum, from VHF to cell phones, satellite phones and beyond. The system can support extended and continuous field operations, by employing ‘hot swap’ of spare batteries.

VIP protection is the forte of the Israeli company SESP, specializing exclusively in RF jamming technology since 1997. SESP is offering a suite of high-power jammers to meet a wide range of applications, claimed to cover all frequency bands that could be employed by potential threats. The company offers custom made, highly reliable jammers, integrated into protected vehicles to provide maximum security for VIPs, military units, SWAT teams and EOD squads, anti-terror units, anti-drug agencies, and other law enforcement personnel.

SESP jammers are fully integrated and concealed into luxury vehicles such as the JAM-V Mercedes S500L and BMW 7 Series. The powerful jammer is installed in the trunk, along with its cooling, ensuring uninterrupted operation in any climate, and power generator feeding directly from the vehicles’ fuel tank, sustaining the jammer with peak power under all driving conditions, without degrading the vehicle’s mobility or comfort. The vehicle is customized with special RF shielding for full protection of the driver and passengers. In addition, the vehicle can also be armored to level B6.

SESP’s Jamkit high-power vehicular multi-band jamming system can simultaneously jam the RF frequency bands most used around the world, including cellular (CDMA, TDMA, GSM, HGSM, etc.), satellite, VHF/UHF and WiFi and Bluetooth frequency bands. The remotely controlled system is installed in separate attaché cases containing the cellular/satellite and VHF/UHF high power jamming units, feeding 350 watts RF output power to 5-8 roof-mounted streamlined high-gain omni-directional antennas. Vehicles are configured with cabling and antennas, while the actual jammers rotated between several vehicles depending on user operational methodology.

Employing high-power jammers, users can often protect a vehicle formation such as a small convoy or VIPs from the threat of roadside bombs, or radio-controlled improvised explosive devices (RCIEDs). This method can be applied mostly in civilian and VIP protection when the group of vehicles maintains close distances, moves and is controlled under strictly disciplined movement drills. Such systems dramatically lower risk of assassination attempts from enemy-deployed explosive devices. For vehicle escort applications, SESP provides even more powerful jammer, designed for integration into four-wheel-dive luxury vehicle, transmitting over one kilowatt of RF jamming signal, resulting in greater radius of coverage around the vehicle.

A derivative of the Jamkit, JAM-V MK4 is tailored for the Toyota Land Cruiser, featuring over 1.3 kW RF output while a concealed configuration of the JAMX jammer, designed for the Hummer H2, covering an extended frequency range, can deliver a combined RF output of over 1.5 kW to act as an escort jammer.

At Milipol 09 Vidisco is introducing two new portable systems utilizing flat amorphous silicon panels – the Flat foX-17 and foX-Rayzor designed for operation with EOD robots. With these inspection systems a bomb disposal technician can analyze images on-site, identify and differentiate organic materials like explosives or drugs from inorganic substances like metals. The new battery operated XR-DE Dual Energy Module, enables automatic detection of organic and inorganic materials to enhance existing pulsed X-ray sources. The new system improves penetration by 200%, allowing for better probability of detection (POD) in IED’s.

These systems are fully integrated on EOD robots, enabling the EOD team to leverage remotely controlled means beyond logistical and disruption functions. Integrated into the robot, the X-ray system is fully controlled over the robot communications link, or separately, over wireless communications, where applicable.

The high power wireless units were developed by the company to give a long range wireless solution. In recent tests the system demonstrated wireless communication distance of 750 m in line of sight conditions. The system demonstrated control distances of 1.5 km using two units.
