DefenseReview plans on taking a close look at Eureka Aerospace’s Impulse Synthetic Aperture Radar (ImpSAR) "through-the-wall imaging technology, which allows the operator to see through walls, as well as their High-Power Electromagnetic System (HPEMS), which uses microwaves to fry a vehicle’s electronics that control the engine’s vital functions.

Before we do this however, here’s some preliminary info (i.e. excerpts) on both technologies, taken directly from the Eureka Aerospace website:…

"Impulse Synthetic Aperture Radar (ImpSar) Technology:

Eureka Aerospace is developing a "through-the-wall" imaging system capable of "seeing" through walls such as drywall, wooden wall, concrete wall and brick wall, using extremely high-resolution transient Impulse Synthetic Aperture Radar (ImpSAR) system. The system is capable of remotely imaging targets such as man, weapons, file cabinets, tables etc on the "other" side of the wall, at large standoff distance.

The ImpSAR operates in a transient, impulse radar regime, where extremely short pulses (approximately 100 ps) having extremely large bandwidth (approximately 3.5 GHz) are radiated using a special impulse radiating antenna (IRA). The presence of the microwave energies in the 250-3500 MHz frequency range assures together with the very narrow pulsewidth, assures adequate penetration through walls and high resolution of microwave images (in the order of 5 cm in both range and cross-range directions).

The key specifications of the ImpSAR system are:

– Capability to image at standoff distance of at least 100 meters
— Exceptionally high spatial resolution of 5 cm in both range and cross-range
— Quick acquisition time (fraction of a second)
— Capability to “see” through drywall, wooden wall, brick wall, concrete wall
— Portable compact system
— System weight and size not to exceed 30 lbs and 4 cubic foot, respectively
— Day/night, all weather operations
— Host platforms include man, ground vehicle, helicopter and UAV"

"High-Power Electromagnetic System (HPEMS) Technology:

The high-power electromagnetic system (HPEMS) uses microwave energy to disable/damage vehicle’s electronic control module/microprocessors which control engine’s vital functions. The system is capable of (1) high-value asset perimeter protection from approaching hostile vehicles, (2) bringing cars to halt on urban, suburban roads and multi-lane highways, (3) perimeter protection for gas-oil (fueling) platform at sea and (4) day/night, all weather clandestine operations. Figures shown here depict HPEMS’ application for stopping vehicles on highways and perimeter protection of gas-oil fueling platform from approaching boats at sea.

The focus originally is to build a compact portable tunable system to be integrated in a police car (Ford Crown Victoria) and having the following operational capabilities:

– Operational range of frequencies tunable in the 350-1350 MHz range
— Immobilizing all vehicles with microprocessors at the range exceeding 50 meters
— HPEMS fits on a roof of a vehicle

Once the car-hosted system is built and tested, Eureka Aerospace will transition the technology to building larger HPEMS for 5-km perimeter protection applications.

HPEMS consists of 3 major elements:

1. Power Source
2. Tunable RF Oscillator
3. High-gain antenna

The power source consists of 16-stage Marx generator having erected voltage in excess of 640 kV, generating high energy (103 J each) pulses at PRF=100 Hz, yielding 10 kW average power. Marx generator is being fed by 270 Vdc capacitor bank, which in turn is energized by a 12V, 2kJ/sec car alternator. The design goal is to achieve PRF=1000 Hz, thus increasing the average power by 10 dB."

Defense Review is interested to see how Eureka’ Aerospace’s ImpSar tech compares to Time Domain Corporation’s RadarVision/SoldierVision tech, which DefRev witnessed in person at TREXPO East 2001. The unit we saw was the RV2000 SoldierVision unit. Time Domain’s latest versions of RadarVision are RadarVision2 and RadarVision2i, and they still manufacture SoldierVision.

Here’s what Time Domain Corporation has to say about RadarVision2 (taken from the RadarVision website):

"The Second Generation Through Wall Motion Detection Radar For Enhanced Tactical Entry (for US use only)

Based on the worldwide success of RadarVision and marketplace feedback, Time Domain, the leader in UWB radar technology, has taken through-wall radar to a new level. Increased sensitivity, vertical view mode, and up to 3 hours of continuous use are just a few of the incredible new features available in this device.

New Features of RadarVision2:

Significantly increased sensitivity
Additional vertical view mode
Tripod mountable
Three operator-selectable ranges
Extended operating time on one battery
New ergonomic design"

Time Domain Corporation on RadarVision2i tech:

"The Second Generation Through Wall Motion Detection Radar For Enhanced Tactical Entry (for worldwide use)

The second generation RadarVision 2i through-wall motion detection device utilizes field-proven UWB technology to deliver the most advanced features and benefits available on the market today. Based on the worldwide success of RadarVision and marketplace feedback, Time Domain, the leader in UWB radar technology, has taken through-wall radar to a new level. Increased range, "stand-off" capability, and more than three hours of continuous use are just a few of the incredible new features available in this device.

New Features of RadarVision2i:

Increased range to 20m
Significantly increased sensitivity
10m "Stand-off" capability
Additional vertical view mode
Tripod mountable
Four operator-selectable ranges
Extended operating time on one battery
New ergonomic design"

Here’s Time Domain’s company info on SoldierVision tech:

"Sense Through The Wall (STTW) Motion Detection Radar For Military Operation in Urban Terrain (for US Military use only)

The SoldierVision through-wall motion detection device utilizes field-proven UWB technology to deliver the most advanced features and benefits available on the market today. Based on the worldwide success of it law enforcement product, RadarVision, Time Domain, the leader in UWB radar technology, has taken through-wall radar to a new level. Increased range, "stand-off" capability, and more than three hours of continuous use are just a few of the incredible features available in this device."
