See Through Wall radar imaging Technology

Here I’ll put all through wall human sensing, localization, tracking and surveillance technologies that are in commercial product stage. Not prototypes, not patents, no university or academic research. Products that are available to law enforcement (allegedly), military and first responders. In wrong hands its a perfect technology to create psychiatric symptoms in anyone.

ERKOS Environmental Radar for a Knowing Observation and Surveillance ERKOS is the SELEX Sistemi Integrati innovative solution for emergency and life-threatening situations. The new hand-held system provides immediate detection of humans behind concrete walls and their continuous tracking, as well as building layout and life signs detection.

Life Signs Detection This function allows to detect life signs, like heartbeat and/or breathing in a through-the-wall context, in particular revealing motionless people in real-time. The detection of still people is performed by illuminating the investigated area with electromagnetic signals and exploiting the phase-modulation induced from the breastbone movement. This feature allows to locate people under ruins in case of landslides, earthquakes and other disasters. Advanced Tracking The system allows to locate and track humans inside the area of interest, both in free space and in a through-the-wall condition, with an improved resolution with respect to Global Positioning System based devices. Tracking is carried out by means of a two steps algorithm. The first step provides the spatial map of targets position while the latter uses this map to perform tracking. The processing is able to remove the presence of spurious objects that could be wrongly identified as persons.

 PKI 7405 (germany)  PKI radarThis device is a small handheld system for the detection and localisation of human beings or animals being suspected in inaccessible rooms. The typical application is during anti-terrorist interventions and disasters like e arthqu akes, demolitions, etc. Its high sensitivity even assures reliable detection of objects hidden behind solid structures like walls, wreckage, etc. According to the micro-movements performed by their life functions the system detects and localises them. In common use, the PKI 7405 can be deployed vertically for forward observing or horizontally for up- and down scanning. The easiest way of operation is just to place the device on the wall or any other solid object. Another possibility is to mount the system on a tripod and to observe the obstacle from a distance of up to 10 m. An optional LAN remote control allows the operator to survey the scene from a safe distance, which is especially useful during long term operation. PKI 7405 has two basic modes, one for fast moving and one for non- or slow moving objects. The fast moving mode has a better tracking accuracy whilst the slow moving mode is more suitable to detect objects which are not moving.
 EMMDAR and RANGE-R® by Cyterra (USA)


Today’s soldiers are faced with asymmetric warfare tactics that require more sophisticated means to locate and engage enemy combatants. As the battlefield spreads to urban areas, soldiers must increase their situation awareness to protect themselves from ambushes, suicide bombers and other potential threats. EMMDAR provides the modern soldier with the operational advantage of increased preparedness when entering buildings that have potential hostile enemies, thus ensuring elevated mission success rates and the ability to save lives.

L-3’s EMMDAR is a lightweight handheld radar system designed to detect people through walls. In seconds, EMMDAR informs the user of the presence of moving or near-stationary personnel and the distance, or range, to the person.

EMMDAR is type classified by the US Army as AN/PPS-26 and is a controlled item under the International Traffic In Arms Regulations (ITAR). EMMDAR may be exported with the proper authorization by the U.S. Department of State.

ranger-30br-nocoin-450pxRANGE-R® is a highly sensitive handheld radar system designed to detect and measure the distance to moving and near-stationary personnel through walls constructed of common building materials. Designed to increase situation awareness in urban environments for its users, RANGE-R provides vital intelligence necessary to safely undertake a variety of law enforcement and search and rescue operations.

RANGE-R applications include:

  • Police / SWAT — Determine the presence and location of assailants or hostages in a building
  • Search & Rescue — Locate injured people inside buildings
  • Firefighters — Quickly determine whether people are trapped in a building

L-3’s patented stepped frequency continuous wave (SFCW) radar technology and proprietary target detection algorithms enable RANGE-R to operate as a highly sensitive Doppler motion detector. Advanced packaging design results in the smallest, lightest through wall sensor available today.

With near immediate analysis and results in seconds, RANGE-R provides first responders with critical information that may make the difference between life and death.



AKELA, through sponsorship by the National Institute of Justice (NIJ), has developed a high performance, portable, see-through-the-wall imaging system. The system provides the ability to detect and track the presence of both moving and stationary individuals within a building structure.

Unlike some through-the-wall systems that must be placed in direct contact or in close proximity to a wall, AKELA’s system provides for a standoff distance up to 30 meters. This helps to keep the personnel operating the system out of harm’s way. It also provides a wider viewing angle, allowing for detections within multi-level structures from a single position.

The provided software allows full control of system operation, signal processing, and graphic display. A display of detection results appears within a few seconds of start-up. The system provides the ability not only to detect an individual person, but also to determine his approximate location in both range and azimuth without the need to relocate the system.

 Prism 200 (UK)  prism_fieldPrism 200 the most advanced portable through-wall radar system in the world:

  • Prism 200 is easy to use,  quick to respond,  and fast to load
  •  With the press of a button, operators can switch between front, plan or profile views for a complete picture and can also observe the scenario in a 3D view
  • Advanced signal processing highlights moving people and objects in complex environments
  • Its ergonomics allow the operative to use it one-handed or two-handed

Covert intelligence

Prism 200 has been designed for dangerous and life-threatening situations, where without invasive sensors it presents reliable information to the user.  Using highly sophisticated software, the unit can analyse radar signals and instantly filter out objects that are not moving behind a wall or door. This means that Prism 200 can be used in a range of different environments – even offices with their angular surfaces and metal objects, which act as a ‘hall of mirrors’ to standard radar equipment. This level of analysis means that users do not waste their valuable time in translating spurious data; they can focus their attention on what is most important – the people inside.

U.S. based TiaLinx Inc. has developed a system, also utilizing a low-power UWB design. Actually, TiaLinx’ Eagle 5 family of radars can be used as ‘dual-use systems’ – for spotting and tracking targets behind walls, but due to its high sensitivity, the sensor can also detecting living people trapped under rubble, by spotting their breathing movements. The system can also detect underground cavities associated with weapon’s caches and IED emplacements inside walls.

The imager ‘illuminates’ the target area with rapid, wide-band high frequency (nano sec.)
pulses that penetrate glass, wood, concrete, dry wall and bricks. The pulses echoed from underground objects and ‘anomalies’ are processes to create a two-dimensional image of the target. The radar can detect objects buried 30 ft deep into the ground or covered by 20 cm concrete slabs.

TiaLinx offers two versions of the Eagle 5 – the Eagle 5P hand held RF imager for culvert and tunnel detection, and -5B model, designed for the detection of underground buried motion. Other models developed by the company are designed as hand held sensors, utilizing a helmet mounted display.

    Looks like we all need to check our local surroundings……trees, telephone poles, fences, etc. These products sound like the perfect tool…..movement, sound AND remote location to PCs. Sinister.

  4. Awareness of such technology should alleviate some stress and uncertainty of the person who is being tortured by such methods. At the moment the only way to defeat uwb radar is metal or water. One would need to transform the living quarters into metal cage or hallow aquarium.

    • That would be really cool though… to live in a hollow aquarium. Wish I had the cash to do it.

    • Billie

      Yes. It does. I think most TIs seem to think they are being monitored by in-house systems. Especially, those TIs that have continual violations of their private homes. Now, it seems, this may not be the case. Much to think about. Thank you for your work.

    Thank you for this beautiful comprehensive table. If the inventors only knew how their technology is being put to perverse, criminal use… Wonder what the ratio of lives saved to lives destroyed is. I’ve long suspected something like this was being used as the perps know whether I’m home or out, what room I’m in, and even where I am in the room, even when I tiptoe around and have all blinds down. It is truly sick. But I’m somewhat comforted to have confirmation of the technology. Hang in there, and keep up the good work. You are helping a lot of us!

      I too tipped around in double sock and soft sandals– trying to escape the hatred of the upstairs tennant. so glad some believe that people can be so vicious in their behavious. MY HUSBAND of 25 years think something is WRONG with me and I was about to move out of the house. Thanks for your knowledge

  9. thank you very much for all the info and links, unsettling reading as it is

  10. the people who were living in the upstairs used to give a running commentary on my movements when i was living in an apartment and i wondered how on earth they were getting such information. without these instruments itself some nosy parkers like this family members creating lot of paranoia in the minds of others and think what will be life on earth when these gadgets come in to these perverted animals.
