Radio Frequency Analysis

ITI approaches each radome order with a thorough review of the customer requirements. With an understanding of the customer requirements, the level of analysis required for each order is determined. Analysis starts with modeling of the material properties and the physical dimensions of the proposed materials to estimate the effects of the radome on the system’s performance. Most applications are a trade-off between mechanical properties and electromagnetic effects, requiring some level of optimization. To validate that the design meets user requirements, ITI uses a number of levels of analysis including:

  • Flat panel loss as a function of incident angle and the radome structure selected
  • Radome-shaped panel loss estimates
  • Simulated antenna Far Field Radiation pattern
  • Simulated antenna Far Field Radiation pattern including seam effects
  • Full-wave characterization of joint or other structural aspects

The outputs of these RF analyses allows system level requirements for boresight error, sidelobe degradation, total loss due to radome, scattering effects, and other system level requirements to be accurately estimated.

Structural Analysis

Structural engineering involves advanced engineering concepts and high standards of application; our team delivers on challenging requirements. ITI uses a three-pronged approach to structural analysis. First, sophisticated Finite Element Analysis (FEA) is used to predict structural behavior. Second, analytical solutions are obtained to verify the results of the FEA, when possible. Third, mechanical testing is performed to validate the FEA and analytical solution accuracy. By comparing test results to analytical solutions, not only are our skilled engineers able to verify the accuracy of their designs, but better understand the loading characteristics of the system and continuously improve future analyses. Safety factors are built into every design. We work in cooperation with our customers to ascertain acceptable riskĀ  levels and design our products accordingly.

ITI can perform structural analysis for the following:

  • Composite (fiberglass/carbon fiber) structures
  • Steel, aluminum, and plastic parts
  • System/Connection assemblies
  • Steel structures
  • Concrete structures

ITI can also provide analysis for parts, systems, and buildings including:

  • Stress analysis
  • Buckling analysis
  • Geometry optimization
  • Vibration analysis
  • Seismic analysis
  • Foundation analysis

CNC Router

Our facility is equipped with a large format overhead gantry 5-axis CNC router. The router has a large working envelope of 20ft x 12ft x 5ft and is capable of milling precision parts. We needed a way to instill higher quality and efficiency into our radome development process. Through in-house milling, we now have the ability to create custom plugs and parts used in the development of our radomes.
