In reply to Anand Gadiyar:
In the datasheet,AWR1243 ouwns three RX and four TX,which means three receiving antenna wireless and transmitting antenna wireless,why?
In reply to user5909325:
The AWR1243 has 3 TX and 4 RX antennas. Having multiple antennas like this allows you to do angle estimation for example. Having a TX antenna placed slightly apart vertically also allows you to do elevation estimation.
Please refer to our training series on this:
Specifically module 1.5 covers angle estimation.
Let me know if this answers your question.
Thank you for your answer,but I has an another question,what is the effect of three TX and How does radar measure altitude?
I don't understand why the radar needs two output antennas and how the radar measures the target altitude.
thanks very much for your answer,I will learn it carefully!
