AWR1843BOOST: mmwave demo visualizer angular resolution

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843

The mmwave demo visualizer shows an angular resolution of 14.5 degrees.
Is this because the AWR1843BOOST antenna has a resolution of 14.5 degrees?

Also is there a way to change this number?

    Hi Yousuke-san,

    Please find my responses to your questions as follows:

    Is this because the AWR1843BOOST antenna has a resolution of 14.5 degrees? -> Yes

    Also is there a way to change this number? -> This is based on the virtual antenna pattern of the AWR1843 and not a parameter that can be set as desired. 14.5 deg is the best resolution you can obtain; however, you can reduce the number of receiver channels and obtain lower resolutions (greater than 14.5 degrees).

    For more details, you can refer to the following App note.
