AWR2944EVM: What's the guideline for selecting scenes on the mmWave Demo Visualizer?

Part Number: AWR2944EVM

Hi TI experts,

In mmWave Demo Visualizer, three scenes can be selected. They are Best Range Resolution, Best Velocity Resolution, and Best Range, respectively.

1. What's the guideline for selecting scenes on the mmWave Demo Visualizer?

2. What is the meaning of "Best Range" literally? Does it mean that I can use this scene to detect the farther range of objects than the other two scenes?

Thank you.

Sean

    Hi Sean,

    Please find my comments below.

    1) There is no guidelines for selection. It depends on the application requirements.

    2) Yes, that will be the meaning. 

    The visualizer user guide will be helpful as well

    Thanks,

    Hi Pradipta,

    I really appreciate your prompt reply and helpful comments. I have further questions and need your advice. 

    1) My application is automotive Radar relevant, e.g. a short-range/mid-range corner radar.  What scene would you suggest me to choose? 

    2) According to you, the "Best Range Scene" is able to detect the farthest object compared with the other two scenes. However, 50m of the "max unambiguous range" is the maximum that I could get no matter how I tried the slider. When I switched to the scene of "Best Range Resolution" and tried the slider, I could get 146m of the "max unambiguous range". Please see the pictures below.

    I am so confused about this result. Why the max unambiguous range in "Best Range scene" is less than in "Best Range Resolution scene"?

    Thank you.

    Sean

    Hi Sean,

    Let me check on the bench once and get back to you with an update on this.

    This is a bug in the Demo Visualizer. We will get it fixed internally. This is not a device limitation. You can refer to radar toolbox form TI to explore more on the maximum range offered by the device. Refer the High End Corner radar project under examples/ADAS

    This depends upon your application requirements. If it is short range or medium range then you can choose form best range resolution or velocity resolution based on the application need.
