A general term used to describe how well a signal will transmit through a Radome but encompasses individual parameters like loss, cross polarization, and copolarization.
A measurement of how much of a signal is lost or absorbed traveling through a Radome, calculated as the amount of power lost by the Radome divided by a reference power. A reference power of 0 dB is often used. The closer this number is to zero, the stronger the transmitted and received signal.
Cross - polarization
Measured in dB, a measurement of how much interference is occurring between a signal in one polarity reaching an antenna in an opposite polarity. The closer the cross polarization is to zero, the more likely a signal will “bleed” into other signals.
Co - polarization
Measured in dB, a measurement of how much of a polarized signal is lost while reaching an identically polarized receiver. The closer the co polarization is to 0 dB, the greater the amount of data is received.
Measured in dB, a sidelobe is a secondary power peak off of the main beam of a transmitted signal. Typically a sidelobe must be below a certain power level in order to avoid any unwanted interference, such as transmitting or receiving to/from unwanted directions. Sidelobes are usually measured in dB relative to the main beam.
A general term to describe the total power loss through Radome in terms of percentage loss or DB loss.
An angular measurement of the diffraction of the RF signal from passing through the Radome, also known as the Beam Deflection Error.
Glass and Window Science
Our patented alumino-silicate glass specifically floated by Saint-Gobain for its Aerospace application. Following its chemical tempering, it achieves unrivaled mechanical properties that allows to design lightweight and reliable windshields withstanding the hardest birdstrike and pressure adverse conditions an aircraft will face through its operational life.
It improves glass mechanical properties through ion exchange: a piece of glass is immersed in the molten salt of an alkaline element larger than the alkaline it contains, an ion exchange arises on its surfaces. This graft of larger ions into the solid structure of the superficial layers makes them highly compressed. It yields a glass, which is logically found much stronger than untreated.
An Indium Tin Oxide (ITO) coating which is applied onto glass surface thanks to a controlled plasma machine. Thanks to Joule effect once power up, this conductive coating provides windshield de-icing capability. Mastering the ITO coating thickness (a few nanometers) is key to ensure homogenous heating of the windshield despite its curved and complex shape, while letting light going through for pilot clear visibility.
