IWR1443BOOST: question about micro doppler analyze

I'm sorry for the delay Zhaoyu, I've asked an IWR team member to take a look at this query for you.

Hello, Akash,

Thanks a lot for your reply.

I am looking forward to the response.

Zhaoyu,

I would refer you to this e2e post: e2e.ti.com/.../614344

Let me know if you can find the information that you need in this post. Please reply if you have any questions.

Hello Kyle,

In radarStudio->postProcessing, there is button for micro-doppler.

I want to know if there is any information about how to realize this part in code level?

Zhaoyu,

In order to realize this in code, you will need very fine velocity resolution, which in turn means a high number of chirps per frame. You will realize this in how you define your chirp profiles. This means more processing and more radar cube memory. The 1642 can support twice the radar cube as compared to 1443. This will mean refining the profile definition of your chirp to increase the velocity resolution. This often results in trade-offs as it relates to maximum range and range resolution.

Additionally, micro-Doppler generally needs additional post processing as this involves a higher level algorithm beyond the standard range, velocity and angle FFT. I would recommend using the 1642 device as you can leverage the on-board DSP for post processing.

Please let me know if you have any additional questions regarding micro-Doppler.

Kyle
