AWR1443BOOST: Measurement differences between AWR1243BOOST, AWR1443BOOST, AWR1642BOOST

Part Number: AWR1443BOOST
Other Parts Discussed in Thread: AWR1642BOOST, AWR1243BOOST, AWR1642, AWR1443

What are the measurement differences between the AWR1243BOOST, AWR1443BOOST, AWR1642BOOST? I've looked through many documents on TI's websites but have not been able to compare measurement performance characteristics.

Specifically, I'm looking for comparisons with:

  1. max range
  2. resolution
  3. frames-per-second

This will help determine my purchasing decision. Thanks for any help!

    Chris,

    The differences between the AWR1243BOOST, AWR1443BOOST, and AWR1642BOOST are highlighted by the processing capabilities of each device. I will briefly describe the differences below:

    - AWR1243BOOST: analog front-end device only, requires external processor; 4 RX and 3 TX
    - AWR1443BOOST: analog front-end with Cortex R4F and Hardware Accelerator (HWA); 4 RX and 3 TX
    - AWR1642BOOST: analog front-end with Cortex R4F and TI C674x DSP; 4 RX and 2 TX

    The differences are in the back end processing capabilities. If you are looking for a self-contained radar solution, I would recommend the AWR1642BOOST. The comparisons you are asking for are not really applicable since the analog front ends are the same for all three devices.

    Regards,

    Kyle,

    Thank you for your answer. I understand.

    However, for the AWR1443BOOST and AWR1642BOOST, doesn't the 3 TX vs. 2 TX differentiate its resolution and/or field of view capabilities?

    Also, if the AWR1642BOOST is recommended, what max range and frames per second does it offer? This information is still unknown.

    Thanks again,

    Chris Monaco

    Chris,

    The third TX on the AWR1443 provides elevation information to the sensor since one of the TX antennas is physically offset from the other two. Otherwise, the azimuth field-of-view is the same for both AWR1642 and AWR1443.

    For the AWR1642BOOST, we are using profile configurations for distances ranging from 80 meters to 120 meters. This is demonstrated in the Short Range Radar lab found in the Automotive Toolbox on TI's Resource Explorer which can be found at dev.ti.com/tirex.

    Regards,
    Kyle
