Hi E2E,
Good day.
Our customer was able to achieve an 80m range using the short range radar lab in the toolbox. However, this range is achieved only for an object with an approximate RCS of 10 sq.m., a bicycle with a lower RCS is detected only up to 20m. What do they need to change in order to extend the detection of bicycles up to 40m? Is changing the CFAR threshold work? If yes, how can they change it?
Regards,
Carlo
Hi Carlo
Lowering CFAR threshold might be helpful but only to a certain extent.
Otherwise one will want to adjust chirp parameters to better enable detection of a bicycle at long distances. For more information here please see the sensing estimator.
Regards,
AG
Hello AG,
Our customer has tried obtaining a configuration from the sensing estimator and tested it, but it did not give the expected results. Here is the configuration file they've used.
The 120m configuration included in the demo files seems to detect bicycles up to 50m with a change in CFAR threshold to 12dB. But the problem now is the GUI is lagging drastically and causing troubles for proper visualization. Is there anything that you can suggest to improve performance? Thanking you in advance.
Regards,
Carlo
Hi,
The gui performance is related to matlab performance running on PC.
It is possible to only display alternate frames. In this way the matlab processing will be reduced
thank you
Cesar
Hello Cesar,
Here is the response I received from our customer:
I don't understand the alternate frame displaying concept. Is the given source code already implementing this concept or do I need to make the changes? On the other hand, it would be nice if you can mention any suggestions to improve the performance of Matlab like changing version, reducing payload size, or changing read interval. Please advise, thank you.
Regards,
Carlo
Hi,
Alternate frame displaying means that the point cloud is displayed only for one out of two frames.The gui code would have to be modified. This is probably related to what the customer mentions by "changing read interval"
Regarding improving the performance of matlab we have noticed that with older versions of matlab (2015 or before) the gui works better.
Thank you
cesar
Hello Cesar,
According to our customer, the GUI seems to work better with the older version of Matlab. But when they record the data received it is only recorded for a short duration. Is there any method to increase this record duration to 5 mins? Also, do we have some references to change the GUI code to display all frames?
Regards,
Carlo
Hi,
The customer can try to increase the value of the "recordingHandle.size"
gui\read_serial_port_and_plot_object_location.m
if recordingHandle.enable == 1
recordingHandle.size = 2^28;
recordingHandle.indx = 1;
recordingHandle.array = zeros(recordingHandle.size,1,'uint8');
end
By default the GUI code displays all frames.
thank you
Cesar
Hello Cesar,
Thank you for sharing the code, according to our customer it works now. However, the GUI seems not to displays all the frames by defaults as for every alternate frame number they see an error frame missed in the Matlab console. Please see the attached file.

Yes, the reason for this is that the Matlab processing is too slow.

For matlab questions customer could find more help on mathworks support forum
thank you
