FAQ - EB-MK ONE

Technical Data

The EB-MK ONE is the most advanced and safe low power radar system available. As a complete system the hardware device contains all needed measurement and analysis as well as electronic processing tools required.

Transmitting Power

The radar sensor of the EB-MK ONE can transmit at a power of up to 100mW. This can be reduced down to 80 or 60mW if required. With this specification the EB-MK ONE fulfills the highest safety regulations and is completely safe to use.

Frequencies

The EB-MK ONE utilises the K-Band of the electromagnetic spectrum at 24 GHz. The transmission frequency can be adjusted between 24,000 to 24,250 GHz with 50 MHz steps. For each step 9 transmission channels are available with slightly different frequencies which allow for multiply systems to be used on the same range.

Precision

The EB-MK ONE measures velocities to a precision of 0,24m/s at any speed. This is done through measuring the true doppler shift for which a shift of ~160Hz equals a velocity change of 1 m/s.

Range

The range for velocity measurements heavily depends on the positioning of the EB-MK ONE . For standard projectiles this is about 30m with higher ranges for large caliber bullets.

Size / Weight

The EB-MK ONE has a size of 25x20x10 cm with a weight of 2.5 kg (5 lbs) with the battery pack attached.

WiFi

The WiFi connection uses the 2,4 GHz band. Only one device at a time may be connected to the EB-MK ONE to control the measurements.

User / Utilization

The EB-MK ONE has been designed with a maximum of user friendliness and compatibility in mind.

Browsers

The user interface can be accessed through the on board web server. The displayed IP address must simply be input into the address bar of a browser to connect to the EB-MK ONE . All common browsers are usable including Google Chrome, Firefox, Safari and many others

Custom Ammo / Weapons

In addition to the already preloaded catalogue of weapons and ammunition the users can add their own entries with all relevant technical data. This includes adjustable drag profiles or BCs for projectiles.

Data Export

All relevant shot data can easily be exported into .csv files which can be accessed with programs like MS Excel (Text needs to be split in columns) or in Google Tables.

Triggers

The EB-MK ONE has two selectable triggers to detect a projectile: A microphone and a radar based trigger. The radar tigger detects a strong enough signal created by any moving object to start the signal recording. The adjustable microphone trigger does this by detecting a loud enough sound.

Connection

The connection can be set up either via a cable (LAN) between the EB-MK ONE and the user device or through a WIFI connection (WLAN) using the antenna. The EB-MK ONE and the users display device simply need to be in the same network which does not need to be connected to the internet.

Power Source

The EB-MK ONE uses a custom battery pack which can power the EB-MK ONE for 6-8 hours depending on environmental conditions. To enable the highest level of precision in the measurements the EB-MK ONE requires a perfectly stable power source and cannot be powered from a wall outlet.

Unit Systems

All units can easily and individually be switched between the metric and the imperial system.

Environment Conditions

The EB-MK ONE can be used in any location and under all environmental conditions. This includes the use indoors as well as in changing lighting conditions and during rainfall.

Technology & Advantages

As the first system to combine the measurement, analysis and ballistic simulation into one device, the EB-MK ONE sets a new standard for ballistic research and performance improvement.

Constant Wave vs. Puls Radar

The use of the constant wave doppler radar technology allows for a much greater number of measurements of the returning radar signal. With the 2.5 to 20 million measurments per second, the EB-MK ONE is capable of detecting smallest changes in the signal which allow for the analysis of the spin and tumble of a bullet.

Calculations Beyond the Measuring Distance

The ballistic trajectory outside of the measuring range of the EB-MK ONE is calculated using individual drag functions for the projectiles and the environmental conditions measured by the on board weather station. Unlike with other ballistic calculators, for example from major ammunition manufacturers, these drag functions can be manually edited by the user to more accurately represent the drag the bullet experiences from, for example, rifles with differing barrel twist rates.

Drag Profiles vs. G1/G7 BCs

The use of the true drag model is the future for ballistic calculations. The G1 and G7 BCs simply compare the ballistic properties of the bullet to a standard projectile. Since these poperties are different at longer distances the use of multi BCs has emerged for long range shooters. The drag profile combines the capabilities of the multi BCs for all ranges and all muzzle velocities.

Wind Effects

Currently the effects of the wind have not yet been integrated into the trajectory calculation. This will be part of the "Drift Analysis" module which will also include the spin drift and other relevant factors.

Shot Exit Analysis

With the use of the constant wave doppler radar technology and the high measuring rate it is possible to detect even smaller particles along with the bullet. With a spectrum analysis of the signal these particles usually show up as weaker signals at slower velocities.

Set-Up

With the level of accuracy and precision the EB-MK ONE offers, the perfect positioning of the radar is key for the best possible results.

Set up Time

With just a little experience the time to set up, connect and adjust the position takes less than 5 minutes.

Best additional Equipment

It is recommended to use a tripod with a large standing area and a minimum load capacity of 5 kg to reduce shaking and vibrations of the EB-MK ONE after the shot.

Position at Weapon

The muzzle of the weapon should be at the same height as the radar sensor to ensure a strong signal. Ideally the EB-MK ONE is set up 5 to 50 cm behind the muzzle so less of the pressure wave hit the sensor. Horizontally, the EB-MK ONE should be positioned 10 to 40 cm next to the barrel of the weapon.

Angles

The radar sensor of the EB-MK ONE has an 11 degree opening angle. The best angle to measure the muzzle velocity (at a range of 50cm) is 12.5 degrees. To measure velocities at greater distances the angle can be reduced to below 5 degrees. The maximum recommended angle is 20 degrees as larger angels can cause accuracy to drop due to slight angle changes.

Down Range Option

Thanks to the radar trigger, the EB-MK ONE can be positioned anywhere along the flight path of the projectile to get a velocity measurement at a longer range.

FAQ - EB-MK ONE EXPERT

Capability

The optional software EB-MK ONE EXPERT is specifically designed for the professional user to maximise and deepen the level of understanding of the measured data.

Data Export

You can download all or selected raw files from the EB-MK ONE to access later or save independently. Alternatively, you can save just the analysis data in ist report form to reduce the data volume.

Raw Data

Using the raw radar data you can detect previously undetectable properties of the bullet during ist flight. This can also be used to potentially improve the positioning of the radar depending on the signal strength.

Trigger moment

See exactly when the EB-MK ONE has detected the projectile for the first time and look back in time in the signal to before the shot was detected.

Rate of Fire

Shot files that have been created in the AF mode can be fully analysed and an extensive shot report is created containing every single shot in the burst. The maximum duration for a burst may be up to 2.4 seconds which will create about 50 mb of raw data.

Recalculating Shot Data

Any raw file can be used to recalculate all results. Some of the conditions of the shot such as environmental factors, positioning and used drag functions can be temporarily changed to visualise differences.

File Metadata

It is possible to view the metadata under which conditions the file / shot has been created. This includes version info, sensitivity settings and much more technical information.

Updates / Devices

Frequent updates with new features and improvements from your feedback

OS / Computer

EB-MK ONE EXPERT runs as a Windows application.

Installation

The installation is done with an installer which will create all required folders in a selectable location. It is started by running the .exe file.

Updating

Updates are installed like the original installation. The installer will automatically update all required files and folders while not removing any user data.

Connection

The connection is established similarly as with the UI. Input the displayed IP address into the labeled field in the "Network Setup" window and press the "FTP" button. If the computer and the EB-MK ONE are in the same network the internal directory will then be accessible.

Offline Mode

EB-MK ONE EXPERT can also be used without a connection to the EB-MK ONE. All raw and downloaded data can still be accessed, analysed and edited.

Drag Profiles

Any ballistician and long range shooter worth their salt knows that, to achieve the best results from ballistic calculations, the true drag model (also known as the “Custom Drag Model” from Applied Ballistics) must be measured.

CD / BC

Profile from BC

If you have previously measured a BC for your ammunition you can use this as a base drag profile. Supported models are G1, G2, G5, G6, G7, G8 and RA4 with others possibly added in the future.

Mach vs. m/s or ft/s

Drag coefficients are always dependend on the speed of sound. However, as no one actually uses mach for their velocities we have added the ability to display the velocity in meters or feet per second under selectable environmental conditions.

CD to BC

A custom drag profile can easily be turned into a BC for a custom range and for different standard projectiles (G-Profiles) starting from an inital velocity.
