Hello,
I have some questions about your Application Report "mmWave Radar Radome Design Guide" as below;
1) About relationship between surface accuracy and wavelength.
In the case of light, if the length of the roughness of object's surface is sufficiently smaller than the wavelength, we think it is not be affected even if the surface is rough.
In the case of radio wave, can we think the same be true of it?
2) About radome thickness accuracy
Desirable thickness of radome is calculated using the dielectric constant of the material and wavelength of frequency used.
Should we how much tolerance can the thickness of radome be kept within?
Example: Calculated radome thickness ±0.05mm, etc.
We are currently in the experimental stage.
Please let me know any information or note about the characteristics of radiation pattern or radiated power passing through radome.
3) About distance accuracy between antenna and radome
Just like question 2) , desirable the distance is calculated using wavelength of frequency used.
Should we how much tolerance can the distance between antenna and radome be kept within?
Example: Calculated distance ±0.2mm, etc.
Please advise.
Thanks for your cooperation.
