Part Number: AWR1843BOOST

For AWR1843BOOST EVM and lab00007_mmr demo, could you please tell the Azimuth range and Elevation range of USRR and MRR respectively?

Hi,

The MRR developer guide specifies this to be around 150m for MRR and 30m for USRR

Thanks.

I would like to know the angles, not the distance.

Hi,

The angle range is dependent on the antenna geometry. If the spacing between antennas is lambda/2, the angular range is +-90 degrees. This is the case with TI EVMs. Source: The fundamentals of millimeter wave sensors app note

The angular resolution does however decrease with an increase in the angle itself. That is also a factor to be considered. Source: Intro to mmWave Sensing: FMCW Radars - Module 5: Angle Estimation. (slides). You can find the formula for angular resolution in the slides.
