PROCESSOR-SDK-TDAX: Capture raw radar data by RVP-TDA3X

Hi supports,

We are working on development of radar system by RVP-TDA3X.
And I want to capture raw data via ethernet.

Firstly, I generated new usecase as below config.
IssCapture -> Select -> NetworkTx (IPU1_1)

And, I tried to capture by your sample code for TDA2 cascade radar. (save 'dataArray' on line 882) as blow.

...\PROCESSOR_SDK_RADAR_03_08_00_00\vision_sdk\apps\src\rtos\radar\src\usecases\cascade_radar_object_detect\radar_cascade_demo.m

I used default radar parameter (width:128,height:128,15fps) for raw dara capturing.
But packet loss seems to occur.
So, I decreased data size (width:32,height:32,1fps) and captured again.
It seems that there is no packet loss but data size is very large(more than 700KByte).

I understand the data size of radar cube would be 49152Byte (2byte×2(IQ)×3(Tx)×4(Rx)×32(width)×32(height)).
Therefore 'dataArray' in your sample code should be 49152Byte.
Is my understanding correct?
If correct, let me know why are data size so big?

Regards,

Kazuki
