MWJ_EMIT_ImageEMIT’s unique multi-fidelity approach to predicting cosite interference provides rapid identification and “root-cause” analysis of EMI issues in complex RF environments.

  • Predict EMI in complex RF environments containing multiple transmitters and receivers.
  • Predict in-band and out-of-band interference effects for all Tx/Rx pairs in the scene.
  • Multi-fidelity modeling approach works with different types of system data allowing predictions using whatever data is available to you.
  • Wide-band Tx and Rx radio models using built-in parametric models or measured data.
  • Multi-port antenna-to-antenna coupling from 3-D patterns or S-parameters.
  • Transmitters and Receivers are modeled using EMIT’s built-in parametric radio models or with actual measured data when available.
  • Multi-channel radio models capture in-band performance as well as out-of-band spurious and harmonic effects
  • Models can be easily refined as more information becomes available. No need to wait for complete detailed information before beginning EMI analysis.
  • EMIT’s analysis engine accounts for all components in the Tx-to-Rx path to compute EMI Margin:
  • Broadband Tx & Rx characteristics.
  • Outboard components such as filters, amplifiers and cables.
  • Broadband antenna coupling using S-Parameters or 3-D patterns.
  • Import geometric models in native CAD formats as well as direct import from EM simulation tools like Savant.
  • Result Summary views identify interfering systems and channels, while detailed EMI Margin plots identify the specific cause of the interference.

EMIT Features:

  • Streamlined cosite interference simulation workflow that allows EMIT models to be created from CST STUDIO SUITE models
  • One step import of CST STUDIO SUITE models into EMIT
  • Intuitive user interface for setting up, running and interpreting an EMIT simulation
  • Computes separate narrow band and broadband EMI margins for a more complete assessment of interference problems.
  • Support for frequency hopping systems (e.g., SINCGARS, HAVEQUICK, etc.).
  • Standard 1-on-1 and N-on-1 analysis modes to predict the effects of multiple cosite emitters on selected receivers including transmitter and receiver generated intermod.
  • Support for a variety of CAD formats including ACAD Facet, Wavefront OBJ, IGES, and IDEAS Universal.
  • Ability to import measured or simulated antenna far-field radiation patterns.
  • Parametric models for common antenna types such as monopoles, dipoles, isotropic, hemitropic, directive beam, loop, etc.
  • Multiple built-in antenna-to-antenna coupling models.
  • Ability to import measured or simulated antenna-to-antenna coupling data including Touchstone and Savant files formats.
  • Library of RF system models. Includes RF models for HAVEQUICK, SINCGARS, Blue Force Tracker, CDL, IFF, GPS, PCS and many other common radios. Also includes models for filters, cables, and other RF components.
  • Parametric models for transmitters and receivers allow RF systems to be built using a minimal amount of information. As additional data becomes available it can be used to improve the basic models.
  • MIL-STD and statistical based models for transmitter and receiver spurious responses.
  • Threat matrix for displaying system-level results in stop light format (Green-Yellow-Red).
  • Multi-core support. The user can specify number of cores to use for a computation through the GUI.

EMIT is a product of Delcross Technologies. It can be purchased through CST distribution channels.
