I have a radar data of size 55*12 with SNR 14db. How do I plot ROC for this data.

Thanks in advance.

Hi Praanesh,

I understand that you want to determine pfa and plot the ROC for the RADAR data with you.

The documentation here will help you to understand about “Detector Performance Analysis Using ROC Curves”. It will also provide guidance to determine pfa and plot ROC curves using MATLAB. Here is another link about “Receiver Operating Characteristics” which could be of help.

Thanks. But I am not quite understanding what am I supposed to do. Can you please let me know how do I proceed further with tha signal I have... This is fairly a new concept to me. Thanks
