Hi

I have designed a development board for the BGT60LTR11AIP, based off of the REF BGT60LTR11AIP MO project provided. I have implemented the SPI configuration and data acquisition using the provide C files in Dave. 

When sending the ADC results to fft_spectrum and then through UART I am receiving the below response:

However I was expecting to see results more like a typical FFT spectrum, as shown below. Can you please advise me, how I can translate these results into the frequency domain rather than plotting each bin. My plan is to implement a similar algorithm to the presence detection one used for the BGT60TR13C, using a fast and slow FFT to recognise new movements in the enivroment. 

In addition for the maximum value from the FFT spectrum (in the first image), I am always triggering as motion detected due to the result is greater than the threshold set in the provided code (30). I understand that this threshold may need adjusted for specific applications however upon testing I have not noticed a significant change in the maximum value when motion is present vs when it is not. Do you have any advice for this?

Here is the schematic for the board I have designed:

Thanks for your help!

Hi, 

Thanks for the last reply here https://community.infineon.com/t5/Radar-sensor/BGT60TR13C-data-to-csv-file/m-p/484400#M2822 .  By this code,  the plot should be of 1 frame and 1 antenna. My recorded signal has 128 chirps/frame and 64 samples/chirp.  so in my  .csv file, the columns are 64 and the rows are 128. I am attaching the file here. When I am trying to plot the columns, the plot looks like this: 

 But in the radar gui, the antenna plot shows like this:  

 When I am selecting single column, I can get a single plot but I want to understand how will i be able to get a single antenna plot like this? And, also this IF data is real but i am interested in retrieving the phase information and how would i do that?  I want to understand this system properly. 

Thanks Sddharth. 

Please tell me about the influence of AC fluctuation of the power supply to VCC of BGT24LTR11N16 on the oscillation frequency.
The phenomenon I observed was that when the VCC power supply fluctuated with a 13kHz sine wave at 50mVp-p centered at 3.3V, the oscillation frequency of TX output fluctuated over a width of 10MHz around the set value of 24GHz.
When the variation is small enough (<<10mVp-p), it varies within 1MHz.
(Other conditions)
・V_TUNE has ±1mVp-p variation at 1.5V input.

  The operating power supply specification is within 3.2 to 3.4V.
I have no idea the possible expected value of this phenomenon as a device behavior.
If the behavior is impossible, please let me know if there are other factors.
 Also, if there are any specifications regarding power supply ripple, please let me know.

Hello, I would like to ask for advice: I inserted the radar into the computer and ran the official demo (Python code). This radar transmits the raw data to the computer through USB, and then the computer executes the corresponding algorithm to achieve distance detection?

Hi,

I want to implement the BGT60TR13C sensor in a design, using an XMC. I was wondering if  there are any example projects for configuring the SPI registers or a more detailed user guide?  something similar to the REF_BGT60LTR11AIP_MO project for the BGT60LTR11AIP sensor. 

Thanks,

Nicole Donnelly

Hi.

Sorry for my poor English as I am not an English speaker.

I'm using XENSIV Connected Sensor Kit, BGT60TR13C Radar + DPS368 Pressure Sensor.

I want to make Range- Angle map with this module, but there is no information about angle data.

I can get range data in meters, so all I need is just the angle data.

If there is any way to get that data, please teach me how to do that.

Thank you.

Hello, everyone:

 I am conducting research on the gesture recognition of millimeter wave radar, but there are few reference codes for the radar BGT60TR13C of Infineon on the Internet.

Do you have relevant information? Or is there any recent news about relevant SDK examples

Hi, I would like to know whether it is possible to use less than 50MHz for the SPI clock speed on the DEMO BGT60TR13C.

The datasheet (BGT60TR13C E6327  Datasheet V2.4.6) states "The SPI interface can be clocked up to 50MHz" on page 26, but on page 28 of the same datasheet, it states that the minimum SPI clock period is 20ns (50MHz).

Please let me know whether the sensor can operate below 50MHz SPI speed and what the range for the SPI clock speed is.

Thank you,
Ming  

Dear Sir,

to minimize the area of antenna design, could we use Infineon 60G 2T4R chip for long distance ~100m design?thanks.
