Has anyone heard of "BakhtarRadar"?
I have received a couple of emails promoting this product. I just wondered if this is something new or just a repackaging of something that has been done before. I'll be doing some independent research on their core concepts, but figured I should tap into the expertise available here as well.
SO...here are the emails. I have nothing to do with this product or this company, just soliciting opinions while trying to learn.

Hello,
I'm sending this circular around to answer questions we've received from various quarters requesting more details about BakhtarRadar and how it compares to sub bottom profilers.
1. BakhtarRadar is capable of operation from a rubber boat (such as Zodiacs) on the surface. It can interrogate the water and the sea-floor.
2. BakhtarRadar can detect to 100-ft of water and seabed. A larger antennae would have to be made for greater depth. Then it should be possible to penetrate up to 200 or 300 feet.
3. We work in the MHz regime at "narrow-bandwidths" with "forced-resonance" allowing us directionality of the wavelength and ability to penetrate into the sea-floor at great depth. If the antennae are submerged at one-quarter of wavelength or less, our ability for detection and target visualization is exponentially enhanced.
4. Results are displayed through BakhtarRadar software generated computer tomography (CT) sections with radar trace numbers directly linked to the coordinate system at which the target is realized.
5. In a majority of cases, we can reconstruct volumetric images and 4-dimensional visualization of targets to enhance our ability for discrimination of targets from clutters commonly found in the ocean. Quality of the images can be improved through deployment of a "stabilizer" device commonly used by Hollywood movie productions.
6. These comparative advantages mean BakhtarRadar is far more applicable and field-oriented than sub bottom profilers. It offers:
- higher resolution
- reduced false positives
- surface coordinates for the footprint of the submerged target for subsequent location, verification and volumetric image reconstruction.
7. BakhtarRadar is by far more cost-effective, easier to maintain and has lower operating costs.
Please feel free to share any further comments or questions.

FYI, I'm circulating some FAQ's that have been asked recently about BakhtarRadar:
1. What are some of the projects you have completed in marine environments?
Most of the work we completed was in conjunction to military and law-enforcement agencies, included, but not limited to: (1) detection and volumetric image reconstruction from plastic and metallic mines laid at the bottom of the ocean along the surf zone; (2) detection and volumetric image reconstruction of mines suspended from the ocean floor; (3) detection and volumetric image reconstruction of a murder weapon (hand gun) in the sea-floor.
2. How does your system compare to the BATHY 1500?
BakhtarRadar works on an innovative concept recently developed in-house and referred to as "forced-resonance" (FR), based on the radar principle as opposed to an "echo sounder" like BATHY 1500. The advantage of using our FR technique is that we can maintain high resolution in MHz regime and still penetrate to greater depth with reasonably small wavelength for detection. In the majority of cases, we can reconstruct 4-dimensional and volumetric images to better discriminate between the target and the many clutters commonly found at the ocean floor. Please note that our output power for ocean/ground interrogation will never exceed 10 dBm (less than 10-mWatt). The energy is forced onto the saline water based on our FR technique, which provides an extremely high signal-to-noise ratio required for submerged target detection.
3. Is it similar to TDEM technology such as the GEM 2?
GEM 2 works pretty much like a magnetometer. Our system can detect both metal and non-metallic targets.
4. Does your system require extensive training? Is it available for lease or purchase?
The technology is available only through a service contract. We would provide our own trained operator(s).
