The Simulator’s Interferer Configuration is a User defined interface for setting the interferer 1 and interferer 2 parameters as shown in Figure: Interferer Configuration and Target Receiver Settings.

The Interferer’s Latitude and Longitude boxes are overwritten each time you click an emitter on the map. Edit the coordinates and click Send Setup to locate the interferer somewhere different than at a location in the emitter list.

User defined Interferer signal frequency.

User defined Interferer bandwidth.

Click the Amplitude Modulation check box to add extra noise to the interferer power level with each sweep, simulating a signal that is amplitude modulated.

Type or select a noise level. The noise types that are set from the pull-down menu are Gaussian or Square. The noise selection is used to inject noise into return data for both sweep traces and IQ data. At a value of 0, very small noise is injected. This is so that each return trace is not identical. Setting it all the way up to 3 will add so much noise that IQ cannot be used to do TDoA. Please note: With IQ data, the noise also increases with distance. So as an emitter moves further from the simulated monitors, the IQ data (and TDoA results) will get noisier until the signal is dropped and TDoA stops.

Set a duty cycle from 10 % to 100 %

Click Square or Gaussian deviation.

Checked assumes omni-directional antennas. When not checked, the interference power depends on the direction between the source and the receiver.

Modulate the amplitude of the interference signal.

Add a frequency hopping signal.

The Simulator sweep default start frequency.

The Simulator sweep default stop frequency.

Displays the options used in a real target receiver scenario.

Set the restart tracking time from 0 to 600 seconds.

To better simulate the return of IQ data, type or select the delay 1 to 60 seconds.

Click the Signal Editor label displays the Trace View window. See Signal Editor.
