AWR1243: How to calculate the elevation angular resolution of four AWR1243 cascaded system

Hi,

Angular resolution will depend on Antenna design.

The example provided in the document mentioned is based on a specific antenna. The angular resolution is determined by diving the Field of View of the Antenna by the number of channels.

For example, for a system with 2Tx antenna and 4 Rx antennae, the number of channels would be 2x4 = 8

If the field of view of the antenna is 120deg, then the angular resolution would be 120/8 = 15deg


Thank you

Thank you. The document says there are another equation to compute angular resolution θres=λ/Ndcos(θ). Where N is the number of  channels, d is the distance between RX.

If we assume  d=2/λ and θ=0, the equation will become θres=2/N.

Can I get the elevation angular resolution of four AWR1243 cascaded system using the above equation (θres=2/N)?

If can, I wonder how to compute the number of  channels (N) in elevation. Thank  you very much.

Hi,

Here is a thread that provides a better explanation for the angular resolution

https://e2e.ti.com/support/sensor/mmwave_sensors/f/1023/t/681263

This thread includes the formulae you mentioned. It also includes the definition of the number of channels.

 

The number of channels in elevation will depend on the antenna design.

 

thank you

Excuse me. Is there any document about the antenna design of four AWR1243 cascaded system?
I have already seen the AWR1243 Cascade document (www.ti.com/.../swra574a.pdf), but it seems no available information i am looking for.
Thank you.

OK. Thanks for your effort.

Excuse me.

If we just look at one AWR1243 system, how to compute the number of channels (N) in elevation?

Thank you.
