Our TargetTrack and SignalTrack software packages provide map based display data from our direction finders.  TargetTrack is recommended for use with our DDF7000 series direction finders.  SignalTrack is recommended for our legacy DDF6000 series equipment.  This page contains instructions on running playback demonstrations as well as instructions on connecting with a fixed site direction finder installed at our office.  Both software packages can be downloaded from our downloads page.

TargetTrack Play Back Demonstration

To view the operation of TargetTrack without a direction finder we’ve recorded two missions and created one training package.  The recorded missions were ran using our DDF7001 packaged systems near our office in Carefree, AZ.  The first recorded mission is a single mobile searching for a beacon transmitter made by Big Red Bee.  The transmitter is programmed to send pure carrier for about 15 seconds followed by 30 seconds of silence.  The second recorded mission utilizes two fixed sites and one mobile site searching for the same transmitter in a different location.  The training package was created to demonstrate the multiple target capability of TargetTrack.

To run the demonstrations download TargetTrack  In this zip file you will find instructions for loading the data and running the demonstrations.

Live Data Demonstration

(NOTE: The live site is currently off the air.  Please contact us if you would like a demonstration.)

Doppler Systems maintains a direction finder site in the Phoenix area that is connected to the Internet.  The site is used for equipment and software test but is normally available and can be used by our customers.  If you would like to use this site, download and install SignalTrack or TargetTrack and download a map for the Phoenix area (press here to download). 


To use TargetTrack, launch TargetTrack.  At the top of the map pane select use the Map Menu and select Open Map. Navigate to where you stored the Area Around Phoenix map and select it. Once the map is displayed right click on the map near Carefree and select Add New -> Fixed Site.  Fill the dialog fields as shown below.  After you’ve connected to the site use the receiver tuning control in the lower left corner of the window to tune the receiver to 162.55 (a local weather channel).  Bearings should be shown emanating from the site pointing slightly south of Phoenix (near the G in Guadalupe).  You can also tune to 162.425 which is another weather station on Mount Ord near Payson, AZ.  TargetTrack requires audio streaming.  To set up audio streaming you will need to port forward port 10001 in you router.  See the technical application note on how to configure your router.

Occasionally this site is down for maintenance and new equipment installation.  If you have trouble getting a connection please e-mail us and we will let you know when the site will be available.

SignalTrack Play Back Demonstration

The data required for the play back demonstration is included on the installation disk that came with your direction finder or it can be downloaded.  The data consists of two playback files and two maps.  Test case 1 is data recorded by a single mobile site trying to find a transmitter.  Test case 2 is a mobile site using data from a fixed site to find the transmitter.

To run the demonstrations download and unzip the demonstration files and save them to a known location on your hard drive. If you haven’t installed SignalTrack download and install it.  Launch SignalTrack and when the wizard starts press the cancel button.  Go to the Maps menu and select Map Menu Builder to display the dialog shown below.  Press the Add button and select Maps.  Navigate to the directory where you saved the maps and select both maps. 

Map Builder

Next select the Carefree 2 map from the Maps menu.  In the File Menu select Playback.  Navigate to the directory where you saved the playback files and select the file you would like to view.  After selecting this file a dialog box like the one shown below will be displayed.

Playback Demo

Use the controls in the playback to start and stop the playback or to fast forward it as you would in any playback of data.  All the controls within SignalTrack function as they would if a direction finder were connected to it.  Use the Insert and Delete keys to capture mobile bearings.
