AWR1443: Question for AWR1443

Part Number: AWR1443
Other Parts Discussed in Thread: DCA1000EVM,

Hi Team,

Customer used AWR1443+DCA1000EVM. Because it is easy to oxidize, he bought a shell and put it up. He would like to know how to test the performance of the radome?

Thanks.

Hello Annie,

You could keep a corner reflector or strong metallic object in front of the radar and look at the received power level of the object peak in the FFT with and without the radome. The difference will provide you are loss in the radome.

Vivek

Hi Vivek,

generally speaking: do radomes effect phase measurements as well or do they only attenuate? If not, DoA estimation is distorted, correct?

Hello,

you are right , they could impact the phase as well. Depends on the shape of the radome, proximity of the sensor etc. So yes, doing amplitude and phase measurements at different angles will be a good way to evaluate.
