Radio Direction Finders and Direction Finding Systems


TargetTrack is our latest and most full featured radio direction finding software.  It was designed around our new DDF7000 series direction finders but will work with our legacy DDF6000 series systems as well.  TargetTrack satisfies the needs of Signal and Communications Intelligence professionals in that it provides audio recording, evidentiary data, archival data, and the opportunity for post collection analysis of the bearing data.

TargetTrack functions with fixed site or mobile direction finders.  It can be used with a stand alone mobile direction finder or it can network multiple direction finders on a Ethernet based network or using radio modems.  The location of each direction finder is shown on a map.  When a signal breaks squelch TargetTrack begins recording the audio and collecting and displaying the measured bearings.  If multiple direction finders are networked it will display the estimated location of the target and a 95% certainty ellipse about the target location.  When the transmission ceases TargetTrack waits a user selected period of time and then saves the recorded audio and bearing data into an SQL database.  The user can tag the data (referred to as an intercept) using a form that has several fields that can be used to identify the intercept.  The SQL database can be searched on these tags and the data played back on the map display. 

TargetTrack features include

The software may be downloaded from our downloads page.  You can try it out using a df site at our office.  See the demos page for details.

Further information on networking fixed and mobile sites is found on the networking page
