E³Expert has the ability to analyze the electromagnetic coupling of several co-located antennas. This page provides a simplified process of cosite analysis. Our video will give a more generalized E³Expert demonstration.
Sample Steps for Cosite Analysis Application: (click images to scale to full-size)
1. Import a Detailed CAD Model
2. Build a conservative CEM model with antenna definitions entered by the user.
3. Define transmitters and receivers, categorizing them by subsystem and equipment.
Precisely manage antenna direction, terminal resistance, and antenna data.
31 predefined signal modulation types.
User-defined signal levels for harmonics.
RF receiver nonlinear options.
Detailed antenna characteristics defining antenna type, size, main beam, side and back lobe gains, polarization, and beam width.
4. Perform a conservative coupling analysis of all system transmitters and receivers
Analysis EMC Safety Margins for all receivers
View plots of the safety margin vs. frequency to see which frequencies are causing the most trouble.
Use power contribution plots to see which emitters are causing the most interference with a particular receiver.
5. Analyze coupling detail.
View Emitter vs. Receptor screen showing individual port safety margins.
Ability to export data directly to a Microsoft Excel file.
Detailed data summery for each specific port-pair interaction.
Graphically plot coupling data to get immediate feedback of interference issues.
6. Apply higher-fidelity tools to pairing of interest
Use the GEMACS high-fidelity tool to get further safety margin computations on a pairing.
Apply GEMACS plot of surface currents to a transmitter of interest.
GEMACS can plot detailed 2D and 3D antenna patterns effected by vehicle structure
