AWR1642BOOST: Micro-Doppler experiment

Ruth Murape

Part Number: AWR1642BOOST

Hi all,

I only have the radar sensor AWR1642BOOST EVM and I wanted to know if its possible to determine and visualise the microDoppler returns of a target such as a drone. If so, how best can that be implemented.

Thanks in advance...

Thanks Amanda for the link. However, I haven't had any luck writing a MATLAB code that reads the .dat file and writing another code for processing to get the Doppler-Time intensity plot which I want.

The closest resource from Tirex which looks similar to what I want is the Occupancy Detection Lab. But It has the Range angle plot - which is OK: I only need to understand its inner workings.

From the attached image, we are shown of the radar processing chain (a) and in (b), we have a screen grab from CCS of the source code imported into code composer studio.

A. Can I please know which of the dozen files in the source code is responsible for:

1.RF Input, ADC Capture

2.FFT Range

3.Clutter removal

4.Heat-map generate

5.Feature extract

B. If I want a Range-Time AND Doppler-Time plot, which specific file(s) and function(s) do I look at?

Regards,
