Embodiment 1
[0072] This embodiment sets forth the specific implementation of the unsupervised radar signal sorting method based on clustering and SOFM in the present invention when sorting radar signals with overlapping parameters. The implementation flow chart of the present invention is as follows figure 1 shown.
[0073] The detailed background of the radar simulation data is as follows:
[0074] The characteristic parameters of the radar signal, that is, the pulse description word PDW is composed of six parameters: the pulse angle of arrival DOA, the pulse frequency RF, the pulse amplitude PA, the pulse width PW and the pulse time of arrival TOA. This example adopts the three characteristic parameters DOA, RF and PW. Radar signal sorting, that is, the value of parameter n in step 2.2 is 3;
[0075] In this example, PDW data software is used to simulate 8 radars with overlapping parameters. Each radar has a parameter that is equal or similar to the corresponding parameters of other ra...
