Observing U shape in range profile with power value in dB

Hi Cesar,

Thanks for your quick response.

In Figure 1, the TI's default object detection use case radar configuration is used to configure AWR 2243 with the help of mmwave studio and mmwave studio postproc Matlab script is used to analyze the data. In Figure 2, used TI's cascade_radar_datacollect usecase to collect the data and post-processed using mmwave studio postproc Matlab script.

The same setup and same radar configuration are giving different results as shown In the below images. In both the plots, we used the log function to plot the range profile in dB. The U-shaped profile is observed only in figure 2. Please let us know why U-shaped profile is observed only in figure 2.

Figure 1: Used mmwave studio to configure the sensor and plot the data

Figure 2: Used cascade_radar_datacollect usecase to Capture the RAW ADC data and plotted in mmwave studio

Thanks & Regards

Hi

Please give us some time to discuss this with the team that performed the data captures for the Cascade TI Design TIDEP 1012

WIll get back to you before mid next week

thank you

Cesar

Actually I have some more questions

What is the cascade_radar_datacollect ?

Have you used

C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\Scripts\Cascade\Cascade_Capture.lua?

or

C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\MatlabExamples\4chip_cascade_MIMO_example\main\cascade

As described in

C:\ti\mmwave_studio_02_01_01_00\docs\mmwave_studio_cascade_user_guide.pdf

Thank you

Cesar

Hi Cesar,

In Method 1 (Figure 1), followed the steps as mentioned in C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\Scripts\Cascade\Cascade_Capture.lua to configure and capture the raw ADC data using mmwave studio in mmwave cascade EVM. Radar configuration in the Cascade_Capture.lua script was modified according to TI's default object detection use case radar configuration

In Method 2(Figure 2), captured RAW ADC data with the help of cascade_radar_datacollect use-cases as mentioned below and converted the RAW ADC data format to mmwave studio format to use C:\ti\mmwave_studio_03_00_00_14\mmWaveStudio\PostProc tool to plot the range power profile.

1. What is the cascade_radar_datacollect ?

cascade_radar_datacollect use-cases are part of vision_sdk which can be used to dump the raw ADC data into the internal SSD of TDA2x. For more details, I have mentioned the use-cases path below.

C:\PROCESSOR_SDK_VISION_03_08_00_00\vision_sdk\apps\src\hlos\adas\src\usecases\cascade_radar_datacollect.

Thanks & Regards
