For clarification of the TDOA functionality, we use the Vision Simulator program to develop the single screen interface as shown in Figure: TDOA Graphical User Interface. Although the simulator does not understand and respond to all Probe SCPI commands, it does respond to the complete sub-set of commands that Vision uses.
Typically, a map is loaded from an existing user file. The TDOA Application Graphical User Interface provides the approximate location of the simulated probes along with a series of locations that are used to simulate RF sources. These RF source locations can represent:
• Interference sources when working with Power of Arrival (PoA) or Time Difference of Arrival (TDOA).
• A series of locations when tracking a moving RF emitter.
Note
The Vision Simulator Program and the simulated receivers do not have regional settings; therefore, the numbers are displayed in US-English notation.
