Hi, we are working on design of radome for mmwave sensors i.e. AWR1843. here is the our calculation for designing radome. are these calculations correct?

Hello Rajesh,

Your calculation looks fine. Just few comments are based on the chirp design you could select the average center frequency and rerun this calculation.

You could refer below graph just for reference on radome thickness at boresight.

Also note these calculations are for boresight, In rectangular radomes as signal travels away from the boresight, distance travelled through the radome increases causing higher errors, Hence you could explore curved (Half spherical ) based radomes.

Thanks and regards,

Hi, section 5 talk about. Radars can see through plastic and glass of any color. what does it mean by this.

Hi,

This means that it is possible to place a radar sensor behind plastic or glass. You will still receive a signal. However the signal SNR will be impacted by the features of the plastic and glass (type, width, shape...)

thank you

Hi, so with glass or plastic also, I have to take care of the calculations given above.

Yes, Radomes are usually made of a type of plastic

thank you
