IWR1843BOOST: Medium Range Radar: What is the unit of values generated by the MRR parser?

Part Number: IWR1843BOOST

Hi Ti,

According this query https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/982040/awr1843boost-medium-range-radar-data-from-usb  . a MRR parser is used to get the data from the IWR1843BOOST for Medium Range Radar. 

All the TLVs has 

"xyzQFormat": 7
And according to https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/661331/awr1642boost-hi-i-am-using-awr1642boost-need-support-in-understanding-uart-log  this forum If data is sent out in the Q format, to convert your x, y values to a distance in meters, you would treat the x, y data as int16_t values and divide by (2^7).
All the TLVs from  IWR1843BOOST for Medium Range Radar has this  "xyzQFormat": 7 specified so do I need to divide all data by 2^7 ? Where can I get information about the unit of the values given by the mrr parser?

    Hi,

    The unit is meter.

    Please check the gui file to understand  how to convert the data that is received from the target

    mmwave_automotive_toolbox_3_3_0\labs\lab0007_medium_range_radar\gui\MRRvisualization\read_serial_port_and_plot_object_location.m

     detObj.x = detObj.x*invXyzQFormat;
        detObj.y = detObj.y*invXyzQFormat;

    Thank you
