Following the said launch, please be informed that these XENSIV™ Radar 24GHz demo kits are therefore discontinued: Sense2Go, Sense2GoL, Distance2Go and Position2Go.
We are transferring our support capabilities towards the new kits. For the discontinued kits, we will reduce and eventually stop our support including telephone, chat, community support forum, or e-mail inquiries. We apologize for any inconvenience caused.

Your Infineon team
we are planning to use the upcoming BGT60UTR11AIP in a new development project. Is there any information regarding countries that do not allow the deployment of 60GHz radar sensors or just allow certain frequency bands/ranges? This seems to be the case for 120GHz radars if i am informed correctly... I have also heard of countries that require radar sensors of certain frequencies to be registered. Regarding this is there anything to keep an eye on with this new chip?
since BGT24MTR11 is not recommended for new designs, I see that BGT24LTR22 has less output Tx power (6dBm compared to 11dBm for BGT24MTR11). Will this affect the detection distance / beam coverage?
Is there a compelling reason to switch to BGT24LTR22 ?
I am using a DEMO BGT60TR13C with #MCU7 Baseboard and the Python3 ifxAvian package and am trying to understand the raw data coming from the sensor after acquiring a frame:
from ifxAvian import Avian
with Avian.Device() as device:
config = Avian.DeviceConfig(
f = device.get_next_frame()
# (1, 128, 64)

I understand that the shape of the array is determined by (rx_antenna_count, num_chirps_per_frame, num_samples_per_chirp).
However I don't understand the individual cell values.
What do the numbers represent? Do they have a unit?
I am running
MCU V2.2 03/2020
I try using Matlab MatlabWrapperConnectOnly.m
in the example files and get the error code "no compatible device found (IFX_ERROR_NO_DEVICE)"
I looked around here and read posts about version issues compatible to the SDK. I think my hard/firmware is up to date,
I just uploaded the newest firmware
Any idea what could be the issue?
I have KIT_CSK_BGT60TR13C and I want to test the sensor for presence detection. There are some parameters to set, shown in the following tables:
I've understood that hight sensitivity could be good for detection micromovements, max_range is the limit in terms of meters for the detection and the thresholds allow to detect the presence or not.
Moreover with setting the mode you could see only micromovements, only macromovements or both.
1.Do you have any experience with this component?
2.Could you suggest me an example of setting for detection face micromovements?
3. Is there a report after the test (with all the information that I have used)?
4.Do you know if on Modus Toolbox and for KIT_CSK_BGT60TR13C is available this :
Thanks a lot for the support.
Step 6 of getting started with the Distance2GoL board involves an optional firmware update. I am wondering what the purpose of this fimware update is/what (if any) additional functionality it provides? I have been trying to flash the firmware but am having difficulty debugging a J-Link installation issue, so I am wondering if I should just skip the firmware update and continue with developing.Show Less
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 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.Show Less
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.
・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?Show Less
