EMpact

Is useful to naval designers at the early conceptual development stage up to acceptance tests of ships.

Modern naval units are becoming increasingly sophisticated and complex, having to operate in different missions and scenarios.

Therefore, the complexity and the number of sensors and systems (communication, radar, EW, etc.) installed onboard have also increased.

EMpact can be used for on-board EMC/EMI analysis allowing the Risk assessment

RADHAZ
The evaluation of the EM field levels plays a fundamental role:
  • In the assessment of the exposure of Personnel (HERP)
  • In the assessment of flammable liquids and fuels (HERF)
  • In the assessment of ordinances and ammunition (HERO)
  • For the verification of the equipment susceptibility limits (HERE)
EMpact computes the EM fields in both near and far field regions of the sources (antennas).

ANTENNA ON PLATFORM
Starting from the stand alone antenna characteristics EMPACT evaluates the installed performance (i.e. in the operative scenario) taking into account the presence of the ship topside structures (e.g. mast). Radiation patterns, Gain, Shadowed Regions and so on can be rapidly computed in several antenna positions to determine the best trade-off between spatial constraints and performance.

RADAR CROSS SECTION
EMpact has a module dedicated to the RCS evaluation that can be used during either the preliminary and either the final phases of the ship design. Starting from the naval CAD, EMPACT allows the calculation of the RCS considering both the effect of the vessel geometry and the materials used

EMC/EMI/RCS RISKS MITIGATION
Once the EMC/EMI/RADHAZ analysis has been carried out Risk Mitigation actions involving Radar Absorbing Materials (RAM), Decoupling Structures (Shields, FSS, etc.), Shaping and Operative Procedures can be suggested.
