Radar signal sorting method and system based on high-order frequency spectrum symmetric Holder coefficient

The invention belongs to the technical field of radar signal processing and in particular relates to a radar signal sorting method and system based on a high-order frequency spectrum symmetric Holdercoefficient. Aiming at the problem that the accuracy of traditional signal sorting based on full-pulse parameters in a complex game scene electromagnetic environment is reduced, intra-pulse features of a signal high-order frequency spectrum are extracted by utilizing a symmetrical Holder coefficient method, the intra-pulse features and stable inter-pulse parameters form a new feature vector, and signals are sorted by using a K-means algorithm; the high-order frequency spectrum symmetric Holder coefficient of the signal is used as an intra-pulse characteristic, and has a larger optimization space compared with a primary frequency spectrum phase image coefficient. According to the method, the features are added into the signal feature vectors, so that the new feature vectors have higher separability, the sorting acc
