AWR1243BOOST: How to capture a large amount of raw data for a long time?

Part Number: AWR1243BOOST

Hi,

I have the set of devices AWR1243BOOST+TSW1400+MMWAVE-DEVPACK to capture the raw data from mmWave sensor. I am using the radar studio in MMWAVE_DFP v00.09.01.06. I followed the instruction in 'mmWave Sensor Raw Data Capture Using the TSW1400 Board' and everything works as expected. 

I tried the following experiment. I want to detect one moving target with 1m/s using the system above and capture the raw data. This is how I collect the data:

1) Set all the parameters according to the tutorial above.

2) Push ' Set up TSW1400'. I got the complete message in the 'output' console.

3) Push 'TSW1400 ARM' . 

4) Wait for about 1 second. Push 'Trigger Frame'

Then I got the raw data with size of 16.8 MB. I read the data. It contains 32 frames, each frames contain 128 chirps and each chirp contain 256 samples. This matches the setting in Radar Studio. However, in the postprocessing, I could not see the moving target. Instead, the sensor could only find the static target behind the moving target. (The peak around 5m is the static target).

I am wondering if there is something wrong in my setup that leads to the failure of detecting the moving target. Thanks!

    Hi,

    In the snapshot you provide please notice the slide control in the upper right cornern.

    By sliding it you will be able to view all the frames

    thank you

    Hi Cesar,

    Thanks for the response!

    I checked all the frames from the data and the results are similar. I think this is because the length for one frame is 40 ms and we only have 32 frames. Thus the total running time for receiver is only about 1.28 s. I am wondering if this is enough for detecting the moving target. Is there some maximal constraint for the number of frame?

    Thanks!

    Hi,

    If the object moves far enough in 1 second, you should see the object detected at a different range in frame 30 vs frame 0

    Thank you
