Welcome to mmWave Sensor Forum!

This forum is for discussions and questions pertaining to mmWave Sensor Devices.  Users can file queries related to mmWave Sensor AWR, IWR devices and their collateral offering including mmWave SDK, Tools and TI RTOS issues in conjunction to these devices.

Please check Learn More About mmWave Sensors for more resources:

Device specific technical documents can be found on device product pages.

When posting queries, please include the following as applicable:

  • Version of mmWave SDK & TI RTOS you are using.

  • Details of board platform (EVM & its revision) you are using.

  • Silicon revision of your device.

  • Version of compiler and Code Composer Studio

  • For API specific issues, please provide the application source code used.

  • For run-time issues, please provide a detailed description of the problem and the expected behavior.

  • Provide/attach relevant Message Log and debug information or screen captures of the issue.

  • Question: What are the main differences between the AWR and IWR devices?


    1. AWR1xxx devices support a wider junction temperature range, -40C to 125C. IWR versions support -40C to 105C.

    2. AWR1xxx devices are qualified for automotive applications as they are AECQ100 qualified and ASIL-B capable. This is not the case for IWR variants.

    3. Specific to the 1642, AWR1642 has 2 CAN interfaces, one of them being CAN-FD. IWR1642 only has one CAN interface (no CAN-FD).

    Question: What is the main difference between resolution and accuracy in mmWave Sensors?

    Answer: It is important to distinguish between "Range Resolution" and "Range Accuracy" as these are two different (but related) concepts. Resolution refers to the minimum distance between two objects that is needed by the sensor to distinguish them apart. As of now the minimum range resolution of mmWave Sensors is just under 3 cm. Accuracy refers to the error in actual distance compared to what is detected by the sensor. As of now mmWave sensors have seen accuracy to within .1 mm under certain conditions.

  • EVM Level:

    Question: I’m having trouble flashing my EVM using the Uniflash Software.

    Answer: We have put together a guide specifically for flashing mmWave EVM’s using Uniflash. This document is available at this link. Please make sure that you populated both the SOP0 and SOP2 jumpers in order to put the device into flashing mode.

    Question: What is the field of view for EVM/BoosterPack? (both azimuth and elevation)

    Answer: +/- 60 degrees in the azimuth (120 deg total) and +/- 15 degrees in the elevation (30 deg total).
