AWR1843BOOST: angular resolution

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843

hi,

as you know, for awr1843, according to the formular, the angular resolution is decided by:

 TI's doc says, N=12, the angular resolution is approximately14.3 deg?

I put this picture here,

if here TI‘s doc makes a mistake? I check my result I calculated 9.55 deg.

my list:

N=4, the result is 28.6 deg.

N=8, the result is 14.3 deg.

please give me an accurate ansower, thanks.

Regards,

  • Hi Wembanyama,

    This is the virtual antenna array for AWR1843.

    To calculate the azimuth angular resolution, you should consider the elements present in the azimuth direction. Here there are 8 elements in azimuth direction. 
    So, N = 8. Azimuth angular resolution = 14.3°

    hi,  there 12 virtual Rx means 14.3°,it's wrong in this doc? thank you.

  • Hi Wembanyama,

    In the document, individual phrases are correct. But the combined statement is incorrect. Virtual antenna array has 12 elements. But for azimuth angular resolution, we consider only 8 elements. So, the angular resolution is 14.3°.
