BOOSTXL-AOA: How to calculate AOA using RTLSCtrl_estimateAngle() function?

Akansha Verma

Part Number: BOOSTXL-AOA

Hi,

How AOA is calculated without using d, lambda in RTLSCtrl_estimateAngle()?

As i am using antenna 1 and 2 of array 1 the ultimately one pair i am using- then what will be the pairAngle[1] in below snippet:

And how to calculate channel offsets, gain and offset in case of Antenna 1 and antenna 2 of Array 1?

Thanks

Hi,

This question is addressed in the known issues thread: e2e.ti.com/.../826180 and e2e.ti.com/.../770218

I hope this will help,

Hi,

I want to know how this averaging of pair angle is calculating AOA?

Because in SLA lab method to calculate AOA is different from this algorithm. How both are similar?

Here we are not calculating any AOA using frequency of channel and distance between antenna.

Please clear this doubt.

Thanks

Hi,

The AOA example uses a method slightly faster to compute the AOA. Instead of doing the full process described in the SLA introduction, we directly use some coefficients computed in our lab. Here is a thread discussing this.
