AWR1243BOOST: Raw ADC to RCS Calculation

Hi

Please search this forum for "RCS". There are several threads that discuss this topic

thank you

Hi Cesar,

Thank you for your quick response. I have gone through several of the posts here in the forum. However, I still have a doubt. For this reason, I decided to open a new post.

I have noticed that most of posts related to the RCS calculation redirects the users to the following answer:
e2e.ti.com/.../634697

However, there is suggested to use the SNR calculation for the RCS value. I just want to understand how the calculation is done. Either for the SNR or for the RCS. If we look at the suggested equation for the SNR calculation, all the parameters I understand how to calculate them except for the thermal noise on the antenna. Can you maybe just clarify me this ?

Thank you again
Santiago

Hi

In this thread, it mentions the following. Does this answer your question?

thank you

"When calculating the SNR , the noise level that you use should be the thermal noise induced noise floor (and not the noise due to clutter).
A convenient way to do this is to have a stationary scenario and use the signal level in the non-zero doppler bins as a measure of the noise floor."

Hi, 

Ok thank you for your response. I understood now how to get the SNR from the post-proc analysis. I just have one more doubt. Some parameters related to the antenna, which are part of the SNR equation, do we take them as the ones suggested on the EVM userguides or AWR datasheet as suggested in:

Thank you,
