AWR1843BOOST: Question about AOA

Hi Bryant,

I could confirm the discrepancy between the two calculations. The AoA DPU calculates wz on the basis of this formula (in the doxygen documentation of AoA DPU):

The +2Wx term corresponds to the third term in the formula above. I have contacted the MRR lab's developer to get clarity on the implementation of MmwDemo_XYZcalc. I will get back to you on this as soon as I have a definitive answer.

Hi Bryant,

The developer of the lab has clarified this. This is not a bug in the MRR lab. I'm told that the method for angle estimation used in the MRR lab is different from that of the SDK AoA DPU. This is the reason behind the difference in formulae used.

Unfortunately, the method used for angle estimation in the MRR lab isn't well documented. If you want to understand it, you would have to go through the code.

Hi Aayush,

I read the sdk code and labs of demo7 code,both AOA  way it has been confirmed that the methods used are the same.

Please check it again.

Hi Bryant,

Let me talk to the developer and see what method is used in the MRR lab. Please give me some time to schedule a talk with the developer, let me get back to you by next Wednesday.

Hi Aayush,

No problem, and let me ask you a question by the way.

Why do you have to measure the elevation Angle and say it's greater than 1 and less than -1,the code is as follow:

if(Wz > 1)

{

Wz  = Wz  - 2;

}

else if(Wz < -1)

{

Wz  = Wz  + 2;

}

What's the theory？

Hi Aayush,

I am waiting the answer,how are you getting on this question?

Hi Aayush,

What's the status of the question about AOA？

Thanks a lot for help me slove the problem.
