CCS/IWR1642BOOST: How to measure angle of object like range and velocity of object using derived data?

Hi, Arpit:

We have some documentation about angle of arrival for xwr1642. You can
1) download mmWave SDK 2.1.0.4 from software-dl.ti.com/.../index_FDS.html
2) look through the doxygen documentation at C:/ti/mmwave_sdk_02_01_00_04/packages/ti/demo/xwr16xx/mmw/docs/doxygen/html/index.html
and search for "Direction of Arrival FFT Calculation".
3) Look through the angle of arrival training on training.ti.com/intro-mmwave-sensing-fmcw-radars-module-5-angle-estimation

What do you mean using "derived data"?

I want to calculate angle from the hex data i am  getting on AR_MSS_LOGGER pin. 

Like in the screen shot below i can calculate distance and velocity.I need this type of equation for an angle and the certain place like i am getting data for distance and velocity in incoming data which i am getting on AR_MSS_LOGGER  pin.

Hi, Arpit:

For each demo, the logging information can be slightly different. Which demo you are looking at now? But in general, the angle of arrival information can be derived from x, y, z location.

z = range * sin(elevAngle);
x = range * cos(elevAngle) * sin(azimuthAngle);
y = range * cos(elevAngle) * cos(azimuthAngle);

For xWR1642, the elevation is not available, only the azimuth angle can be calculated from:
x = range * sin(azimuthAngle);
y = range * cos(azimuthAngle);

Notes that here the azimuth Angle is in the range of (-90~90). If a target is placed in front of sensor, the azimuthAngle is 0 degree.
