Hello all,

I'm developing low-level processing on a BGT60TR13C demo board with the help of the SDK and the Python Wrapper. Here are the steps I actually did:

1. Retrievement of raw-data
2. Range-Doppler FFT for each RX antenna
3. CA-CFAR
4. Angle of Arrival based on complex-angle difference between Range-Doppler map of RX antennas.

From the step 1 to 3, all look good. But I have a problem on the the Angle-Of-Arrival. I have an angle shift of arround 30° in the E-plane. Because Range-Doppler map is coherent, I think the problem comes from a bad phase shift between RX antennas. So the question is, is there an factory calibration of RX antenna?

Thanks in advance,

François

Hi, I noticed somebody else was having difficulty compiling the sketch Radar_pulsed_Doppler_LED on their Demo Radar BBXMC4700 demo board. So on a completely fresh machine installed as per the discussion link https://github.com/Infineon/XMC-for-Arduino/tree/24Ghz-radar Jlink installed, Arduino IDE 1.8.2. XMC version installed 1.60. in the boards menu additonaI libraries set to ARM DSP /ARM NN Framework. Can list all of the errors but here is a snapshot , so predominantly the errors are undefined reference, which I think points to an incorrect path somewhere. I can compile and upload Die Temperature measurement in Device control XMC with no problems and the serial output is fine.

Hi every one,

My questions are about the KIT BGT60TR13C EMBEDD( https://www.youtube.com/watch?v=pUuSCDY14nw)

By downloading the config tool on this page, one can raise an alarm if a presence is detected. Also, the config tool returns the range of the detection.

My objective is to get the raw data from the MADC integrated in the BGT60TR13C chip with this KIT BGT60TR13C EMBEDD.

Is it possible ?

I don't know if it is possible because I think that puzzle pieces are missing:

- I have downloaded  the modus toolbox and the BSP of this product  is available in the project creator under PSoC6 BSPs but there is only an HelloWorld and an empty project, there is no project allowing presence detection.

- The config tool available online allows to reflash the board, but I could not find the bin file firmware anywhere on the web. Does anyone manage to find a firmware for this board and reflash the board with it ?

- Also, I could not find the board schematic. I only know that the MCU is a PSoC6, that the radar chip is the BGT60TR13C and that those two components are linked with SPI communication. 

Thank you very much in advance for your help

Hi 

I have a question about extracting radar data from my BGT24LTR11 shield and XMC4700 board 

What I want to do is visualize "Target Signal Strength" like how it is in the Radar GUI App on a small screen (e.g. raspberry pi screen - Google Search)

Is there a way I can program the XMC4700 board itself to present this data on the screen when I plug it in, or will I have to use another microcontroller with, for example, MATLAB installed to process then present this data on the screen?

Let me know if this is unclear! 🙂

Thanks

Hi everyone, I write a program in c++ using radar sdk 3.2.1 and I found a discrepanse between documentation and function. In particular the problem is in the function named ifx_rai_run_r (and ifx_rai_run_rc) in the params input that in the docs is in form numAntennas x chirps x samples but I found in the RangeAngleImage.c that in line 311 (ifx_cube_get_slice_r((ifx_Cube_R_t*)input, ant_array, &rawdata_view); // set view to the rx antenna for raw data matrix)
it gets slice and not row to get single antenna data, infact the function not working.
Please can it be corrected or give me an example how to use it.
Thanks in advance

Hi,
Please let me know the theoretical angular resolution of the BGT60TR13C?
I think that it is depended on the distance between the Rx ANT. Is it correct?

Best regards,

Has anybody tried to install ifxdaq on a nvidia jetson nano?

I gave it a shot but I got an error which says the platform was not supported. Any workarounds?

Hello i use Radar fusion GUI do recording and get the xx.raw.txt data.

0.4884
0.484005
0.477167
0.47326
0.477656

i know the data (0.484005) from analog signal do ADC convet it to value in [0, 1] in default setting.

while i have some question about the raw data.

=> first question about the data, what does the value 0.484005 or 0.477167 means?

does it means the  amplitude of the size in analog signal after convert to digtial signal?

=> second question, does the radar sensor data can convert to point cloud data, if yes, how can i do that with SDK api.

thanks

I have an BGT60TR13C sensor,  and my radar SDK version is v3.2.1, it's only have presence detection and segmentation  example apps,  is radar SDK(v3.2.1)  has capable(APIS supported or existing algorithm) to get  rate & breathing rate? and would you share me the example codes?
