Radar sensor Forum Discussions

Hello

Is there any firmware available for BGT60TR13C  module to send out some information about the direction of the movement or angle values? 

I'm running presence_detection 1.3.0 but it seems it only transfers distance information not direction. Thanks in advance. 

I hope this is the right forum

Sorry if this is a simple question, I am new to this software. How do I build the C code provided in the C:\IFX_D2GL-HW-SW_V1.0.0\Firmware_Software\Communication Library\ComLib_C_Interface

I want to build the d2gl_basics application but I am unsure how to do this. Could anyone send some steps on how to do this?

Also another quick question, can I do this on a linux machine?

Cheers

Hello,
Is there any function in the SDK that I can use to retrieve the Azimuth and Elevation angle from the radar data?
I know the SDK has the Range-angle image algorithm, but I didn't find any example that uses this algorithm. Is it possible to use Range-angle image for this? Is there any example that uses this algorithm?

Thanks,

Lucas

i have an BGT60TR13C  sensor, is there has algorithm to recognize people's posture? such as stand or sit down or gesture .

is there has sample app in radar SDK?

Hello,

I develop my own algorithm.And I have a question about raw data.

Getting the raw data seems to be using frame_info->sample_data

Is to use uint16_t radar_get_frame(Radar_Handle_t device, Frame_Info_t* frame_info, uint8_t wait_for_data) in radar_base.c?

And how can I achieve complex style like matlab paradigm. (ex: 0.5008547 + 0.5177045*i)

Is sample_data = sample_data(1:frame_info.num_samples_per_chirp,:,:) + 1i * sample_data((frame_info.num_samples_per_chirp+1):end,:,:); complete the complex style in matlab?

Because my algorithm is based on matlab,so I need the raw data in complex style

Please reply back with how to get complex raw data like matlab in DAVE IDE.

Thanks

Hello
I'm using the DEMO POSITION2GO radar, and I'm trying to develop my own algorithm with DAVE IDE.
The COM port will not work when two arrays do calculations or assignation.
But the build is successful.
Below is the code I found problematic.

1.do assignation

double _Complex x1[2][128] = {};

getdata()

{

    double _Complex rx12[2][128] = {{0.5008547 + 0.5177045*I,0.6893773 + 0.5008547*I, ...... };
    int i, j;
    for(i=0;i<2;i++){
        for(j=0;j<128;j++){
            x1[i][j] = (rx12[i][j]-0.5-0.5*I)* 2；//Doing this line will cause the COM port to not be read
        }
    }
}

2.do calculations

void fft1
(double _Complex x[][128],int pekora)     /*fft1(x1,0); double _Complex x1={{0.5008547 + 0.5177045*I,0.6893773 + 0.5008547*I,0.9377289......};*/
{
    double _Complex fev[213]={};
    double _Complex F64[213][64] = {{1.000000 + 0.000000*I,1.000000 + 0.000000*I,......};
    double _Complex f;
     int i, j,g;

    P = 128/2；
    if(pekora == 0){
        if(P==64){
            for(g=0;g<16;g++){
                for(i=0;i<213;i++){
                    for(j=0;j< P;j++){
                        f = F64[i][j]*x[g][2*j];     //Doing this line will cause the COM port to not be read
                        fev[i] = fev[i]+f;
                    }
                }
            }
        }
    }
}

I don't know why the USB COM port is not being read.

Can you give me some advice to fix it?

Any help would be very welcome.

thanks

my sensor is work well  with windows,

but when i plan  connect the sensor with ubuntu(20.04),

and try to run range-angle-map.py,

there has an error like below:

Traceback (most recent call last):
File "range-angle-map.py", line 122, in <module>
with Device() as device:

and if i run command "lsusb" in linux,

is there has any idea for it?

Hello!

Im using Distance2GoL (Software-Controlled FMCW radar) 

I am trying to obtain the distance parameter when running the example C-Code. However the only printed output doesnt seem to be sufficient to calcualte the distance. And i cant find the distance elsewhere in the code aswell. 

The printed data aswell as the corresponding part in the in code is attached. The code is commlib24_D2GL_basics.c line 555.

"Sample-Data" seems to be a float between 0 and 1 but im not quite sure what that represent. When im trying to use the formular for the distance R in the documentation im missing the variable "fb (beat frequency corresponding to the target).

Is it even possible to extract the raw distance data when using the c-code? I am planing to use the distance as a live parameter for a sound project. 

Thanks alot!

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?
