In this section you will find some of the tutorials and white papers that L3 ESSCO has published over the years. After reading this material you will come to understand why L3 ESSCO has been considered the world's leading authority on radomes since 1961.  To this day, many of the papers L3 ESSCO has published has set industry standards, and been adopted for determining radome performance.


  • IFR Definition
    Every large radome has joints in order to put the radome together.  These joints have EM wave scattering properties that are very different from the scattering properties of the panel surface and thus, the EM distortions introduced by the joints have to be accounted for separate from those introduced by the panel.  To account for these distortions the radome industry adopted what is referred to as the IFR (Induced Field Ratio) approach to determine the overall scattering levels of the radome and thus their performance.

  • The Importance of Hydrophobic Coating
    It has been well documented for years that water on the surface of a radome has a negative effect with regards to antenna performance. This tutorial provides information on the importance of using hydrophobic coatings to minimize transmission loss in rain environments.

  • Noise Temperature of Metal Space Frame Radomes
    In a Metal Space Frame Radome many engineers assume that the total transmission loss of the radome is made up of the the losses due to the dielectric membranes plus the loss of the metal space frame.  This is not the case and this tutorial provides information on all of the components that make up the total transmission loss of a metal space frame radome.

  • Using Metal in Radomes
    For many years it was assumed that metal should not be used in front of an antenna aperture as it would block RF energy.  Learn why the use of metal in some parts of a radome will actually provide better overall performance.

  • Radome Selector Guide
    The Radome Selector Guide provides an overview of the four major types of ground based radomes.  The guide will help you in choosing the best radome for your application.  In cases where this is not clear, we recommend that you contact us and let one of our sales professionals determine the best radome for your needs.
