Part I: Welcome to the RaDeKL Radar GUI
Introduction
The RaDeKL Radar GUI provides a simple-to-use interface to the Multispectral Solutions’ RaDeKL Radar
device, allowing for the graphical display of radar data as well as the configuration of various operational
parameters and settings as well as record/playback of radar data in real-time. This document familiarizes
the reader with the features of the RaDeKL Radar application.
Note: Before the RaDeKL Radar unit can be used, the appropriate USB driver must be installed.
Refer to the appendix at the bottom for instructions.

RaDeKL Radar User’s Guide
1.
Display Selection
Select the type of graphical display:
a. Amplitude: An X-Y graph with range bin numbers (approx. in feet) across the X-axis and radar
return value across the Y-axis.
b. Waterfall: Continuous time display with range bin numbers (approx. in feet) across the X-axis
and a color-coded radar return values flowing down the top in continuous mode.
2.
Filter Settings
These filter settings are applied after the data is returned from the radar:
a. Off: no filter is applied.
b. Averaging: Autoregressive smoothing filter (low-pass) over time. Enter a coefficient between
0.000 and 1.000 and click “Apply” to smooth the radar return value over time. This will make
abrupt changes appear more smooth
c.
3.
MTI: Autoregressive background subtraction filter (high-pass) over time. Enter a coefficient
between 0.000 and 1.000 and click “Apply” to highlight changes from the previous sample over
time. This filter makes it easier to detect sudden changes in the field of the radar.
Clear Display
Clicking this button clears the graphical display area.
4.
Display Area
The graphical display area. This is where the radar data is displayed in graphical form, either as an
amplitude or waterfall chart.
5.
Status Line
The status line shows the status of the radar or the last action requested, along with an icon indicating
the run status of the radar or playback file.
6.
Range Bins
The X-axis of the display area labels the range bin (1-256) displayed horizontally. Each range bin
represents a 1-nanosecond interval, which is roughly equivalent to 1 foot. The exact range bin intervals
are 11.8 inches (30.0 cm) per range bin.
7.
Zoom Buttons and Scrollbar
Zoom horizontally up to 8 times. Once the zoom setting is greater than 1, use the scrollbar to move
horizontally over the entire range of range bins.
Note: If your PC is slower than 800 MHz or is very busy with other tasks, using a zoom setting of 8
and a Sample Interval of 50 ms (in continuous mode) may result in display lag or even an I/O error,
since the application will no longer be able to keep up with the incoming data stream.
8.
Radar / Playback Tabs
Switches between active radar and playback modes:
a. Radar: Data is displayed from the actual radar unit attached to the computer.
© Multispectral Solutions, Inc. 2006
RaDeKL Radar User’s Guide
b. Playback: Data is displayed from a previously recorded file containing radar data. See the
Playback Screen Layout section below for details.
9.
Radar Device Selection
a. The pulldown menu allows selection of the desired radar device, if more than one device is
connected. It always shows the currently open radar serial number. Selecting a different radar
using the pulldown menu automatically opens that radar unit for operation.
b. The Description shows the description string, followed by the version of the open radar unit.
c.
Reset Radar button: Perform a hard-reset on the radar unit.
10. Run Radar Buttons
a. Single: Collect a single radar sample (i.e. all 256 range bins for a given snapshot) and display
the data in the display area.
b. Continuous: Start collecting continuous samples according to the Sample Interval setting and
display the data continuously in the display area.
c.
Stop: When in continuous mode, stop the radar.
11. Record
Record radar data to a file for later playback. When the recording is started, a dialog box asks for a
filename.
a. Single Sample: Record a single sample into a file.
b. nnn Samples: Specify a specific number of samples to record to a file. If the radar is not in
continuous mode, continuous mode is temporarily started to record the requested samples.
c.
Until Radar Stopped: Record radar samples until continuous mode is stopped. If the radar is
not in continuous mode, continuous mode is automatically started.
12. Radar Settings
Configure the operational settings of the radar device. These settings are saved in the computer’s
registry and are automatically used when the same radar is opened again.
a. DAC Thresholds: Set the linearity of the radar’s sensitivity to the return signal. You may select
linear, linear/log (linear at first, then logarithmic), logarithmic or custom. Selecting custom
shows a dialog box that allows custom linearity templates (i.e. DAC Thresholds) to be defined
and saved with user-defined names. DAC Threshold values must be between 20 and 227.
b. Tx Attenuation: Control the transmit attenuation of the radar by selecting a dB value from the
pulldown menu.
c.
Rx Attenuation: Control the receive attenuation of the radar by selecting a dB value from the
pulldown menu.
d. Range Delay: Set the range offset of the first range bin returned by the radar. For example,
selecting 32 feet will cause the display to start at 32 feet along the X-axis.
e. Sample Interval: Sets the sampling interval for continuous mode. For example, 50 msec (the
default) will cause a sample to be collected and displayed 20 times per second when the radar
is in continuous mode.

of individual items.
Part II: Usage
The RaDeKL Radar application is very straightforward and intuitive to use. Grayed-out buttons indicate that
the corresponding function is not allowed within the current context. Follow these steps:
Setup
1. First, ensure that you have the FTDI USB driver installed (see appendix below).
2. Ensure that you have the RaDeKL Radar device plugged into the USB port and that the device is
powered up. Point the radar unit in the desired direction for measurements.
Display Radar Data
1. Run the RaDeKL Radar GUI application (there should be a shortcut in the Start / Programs menu).
2. Ensure that desired radar unit is selected under “Select Radar Device” (if there are multiple units
connected).
3. If you get a warning message saying that there is no RaDeKL Radar device attached, ensure that
the radar unit is properly connected and powered up and also that the FTDI USB driver has been
correctly installed (see appendix below).
4. If no radar device is connected to your PC, the application will automatically switch to Simulator
mode, giving you access to four simulated, but fully functional radar devices. These allow for testing
or demonstration of the GUI without having an actual RaDeKL radar device attached.
5. Under “Run Radar” Click either “Single” or “Continuous” to display the data collected.
6. Adjust the orientation of the radar unit as needed.
7. Play with other settings as desired to get the output you need. Note: For most settings to be
changed, continuous mode must first be stopped, the setting changed and continuous mode then
restarted.
8. To save radar data to a file for later playback, click the appropriate button under “Record”. A
standard Create File dialog box will ask for file name and location of the saved TEXT file.
File Playback
1. To play back a previously recorded, click the “Playback” tab.
2. Under “Playback File” click “Open” and select the desired data file.
3. Use the “Playback Controls” to play and/or navigate the file.

Part III: Appendix
USB Driver Installation
The RaDeKL Radar USB port is based on the FTDI FT2232C USB Chip, which requires a driver to operate.
Note: Do not download any updated drivers directly from the FTDI website! The RaDeKL Radar
uses a custom PID (Product ID) in the USB definition and therefore requires a custom driver.
Please use only the driver provided with RaDeKL Radar devices.
Before the RaDeKL Radar device can be used, the USB driver must be installed. This driver can only be
installed if a RaDeKL Radar device is physically plugged into the USB port. Windows then detects the
presence of a new USB device and uses its Plug & Play feature to aid in the installation of the driver.
Please follow these steps:
1. Ensure that you are running Windows 2000, Windows XP (or newer) on the target PC and that the
PC has an available USB 2.0 (not 1.1 or 1.2) port. Have an A-B USB cable ready.
2. Extract the distribution ZIP file, containing the API and driver files. Note the location of the resulting
folder. It should contain a sub-folder named “Driver”.
3. Connect the RaDeKL Radar device to the power supply and insert the power supply into a suitable
electrical AC outlet (120 VAC).
4. Connect the RaDeKL Radar device to a free USB 2.0 port on your PC or laptop.
5. Windows should detect the new USB device and start the Found New Hardware Wizard.
6. Windows XP:
a. Click “No, not at this time” and then “Next”.
b. Click “Install from a list or specific location” and then “Next”.
c.
Click “Search for the best driver in these locations” and “Include this location in the search”.
Click “Browse” and navigate to the folder noted in step 2 and then down to the “Driver”
folder. Click “OK” and then “Next”.
d. Windows XP will find the correct MSSI IUO driver and display a warning about the driver
not having passed Windows Logo testing. Click “Continue Anyway”.
e. Windows will then detect a second USB device. Repeat the above steps for Windows XP to
complete installation.
7. Windows 2000:
a. Click “Search for a suitable driver for my device”. Click “Next”.
b. Check the box “Specify a location”. Click “Next”.
c.
Click “Browse” and navigate to the folder noted in step 2 and then down to the “Driver”
folder. Select the file named “FTDIBUS.inf” and click “OK” and then “Next”.
d. The driver will install. Windows will then detect a second USB device and the driver will
install automatically.
8. Note: The additional USB device installed represents an unused internal port on the USB chip. This
port is not used by RaDeKL Radar and can be entirely ignored. However, during driver installation,
Windows will detect this unused port and insist on installing a driver for it.

9. The RaDeKL Radar is now ready for use. The driver needs to be installed only once for each PC. If
it ever needs to be upgraded, use the Windows Device Manager, ensuring that the radar device is
physically plugged in and powered up.
