Dataset Annotations

Annotations are embedded in file name. A sample image name is "image00001_01CWI_jsr15", Each name can be splited into THREE fields. Those fields are explained as follows.

• image_index:The index number of the image under the corresponding category
• type: Classes of jamming in GNSS
• JSR: JSR of the corresponding image
  <type = ["00Clean", "01CWI", "02DME", "03HookedSawtooth", "04Linear", "05Triangular", "06Triangular-<br>Wave", "07Sawtooth", "08Tick", "09DSSS", "10NBFMJ", "11BLGNI"]>
<JSR = [15, 50]>

Dataset Generation

We publish the code for generating MFGJ datasets in the MFGJdata_Generate folder, so that you can generate a customized number of MFGJ datasets according to your needs.
