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.
