Jamming & COMJAM – Electronic countermeasures from PLATH
Control in the electromagnetic spectrum — at all times
In modern threat scenarios, information and communication are crucial to safety and success. With our jamming and COMJAM solutions, we give you strategic superiority in the electromagnetic spectrum (EMS)
Powerful solutions for maintaining strategic superiority in the electromagnetic spectrum (EMS) at all times.
Whether against enemy communications, to suppress enemy signals or to protect your own connections — PLATH offers proven, powerful solutions for tactical and strategic requirements.
Technology & Functionality
Our jamming systems cover a wide frequency spectrum — from HF (1.5–30 MHz) to V/UHF and lower SHF (up to approx. 6,000 MHz). This makes them suitable for a wide range of applications — from rural areas and urban settings to complex mobile operations.
All systems include:
- Broadband monitoring and signal detection
- Detectors and exciter units for targeted jamming signal generation
- Powerful amplifiers and suitable antenna systems
- Support for various jamming modes — including hopper follower mode for reliably jamming frequency hops and changing communications
Depending on the task, we offer tailor-made solutions — from compact, quick-deployment sets to fully integrated environments for tactical or strategic missions.
Area of application & target groups
Our jamming and COMJAM solutions are ideal for:
- Security and police forces (e.g. anti-terrorism, border protection, crisis intervention)
- Military units and armed forces worldwide, in tactical and strategic areas
- Authorities and organisations with security tasks (BOS) that need to ensure communication monitoring and communication security
- Integrators, system houses and partners looking for tailor-made, reliable jamming/EW solutions for their platforms
Our solutions
An overview of our solution portfolio in the field of jamming & COMJAM
AJS 30R | HF Jamming System
Powerful RF jamming system (1.5–30 MHz) for semi-mobile or stationary platforms
The AJS 30R is a high-power jamming system for the frequency range from 1.5 to 30 MHz. It is primarily intended for integration on semi-mobile platforms for land-based deployment, e.g. a truck-mounted shelter, although integration at fixed stations is also possible. The electronic components, designed for operation in a controlled indoor environment, are 19” rack-mount units.
The AJS 30R provides an ECM capability that allows operations against undesired communications networks in the high frequency (HF) band. The AJS 30R mainly consists of a versatile and fast wideband detector and exciter unit (WDEU), a high-performance power amplifier unit (PAU), and omni-directional receive and directional transmit antennas that are suitable for field deployment in a tactical application.
AJS 2700C | Transportable Jamming System
Compact and portable – with medium to high transmission power for 30–2700 MHz
The AJS 2700C is a compact, quickly deployable and flexible jamming system for medium to high transmission power for the frequency range from 30 to 2700 MHz.
The AJS 2700C provides an ECM capability that allows jamming and deception operations against various undesired communications networks in the VHF and UHF bands. With its ECM electronic equipment (wideband detector and exciter unit, power amplifier) integrated in a rugged transport rack case and including a control laptop PC, receive and transmit antennas, two 8-m field masts, cables and a portable AC power generator, the AJS 2700C is ready-for-use. Thanks to its man-transportability, the AJS 2700C is a versatile asset for missions where bigger, integrated systems cannot be deployed.
AJS 6000R | Broadband jamming system
High performance & integrable into semi-mobile platforms – for 30–6000 MHz
The AJS 6000R is a high-power jamming system for the frequency range from 30 to 6000 MHz. It is intended for integration on semi-mobile platforms for land-based deployment, e.g. a truck-mounted shelter. The electronic components of this ECM system, designed for operation in a controlled indoor environment, are 19” rack-mount units.
The AJS 6000R provides an ECM capability that allows operations against undesired communications networks in the VHF, UHF and lower SHF bands. Depending on the specific mission, the jamming system may be operated either in the frequency range from 30 to 1000 MHz or from 1000 to 6000 MHz. The AJS 6000R mainly consists of a versatile and fast wideband detector and exciter unit (WDEU), two separate high-performance power amplifier systems (PAS), and suitable receive and high-gain transmit antennas.
AJS 2700P | Man-portable Jamming System
The AJS 2700P is a man-portable, rapidly deployable and flexible jamming system suitable for low-profile and concealed missions. It features a very high output power for a system of its size and weight and can jam communications in the frequency range from 30 to 2700 MHz.
The AJS 2700P provides an ECM capability that allows jamming and deception operations against various undesired communications networks in the VHF and UHF bands. It is a very versatile asset for missions where bigger systems cannot be deployed, especially in remote areas. With the supplied battery unit, the AJS 2700P can typically operate for up to 27 hours in monitoring mode and up to 3 hours when continuously jamming. Using reactive jamming modes, such as hopper follower, operation duration with a single battery charge is significantly increased.
EagleEye 320
Advanced drone defence system
The PLATH Anti-Drone System 2100 “Eagle Eye” is an advanced, transportable and fast deployable Counter-UAV system that is able to protect sensitive areas like event venues or critical infrastructure against illegal intrusion of leisure and commercial UAVs. The system is designed to detect UAVs at long ranges, track and tackle them by electronic countermeasures.
PLATH ADS2100 “Eagle Eye” uses a high-resolution frequency-modulated continuous-wave (FMCW) 3D radar, thermal and daylight cameras for UAV detection and classification and a radio frequency (RF) surveillance sensor to detect and identify UAVs at ranges of up to several kilometers. Once the threat has been identified, an integrated advanced multi-band (up to 6) RF jammer can be used to disrupt the link between the UAV and its remote control and/or disturb its GNSS-based navigation.
