The traditional radar signal sorting technology is faced with severe challenge as the electromagnetic signal environment is increasingly dense and complicated.Some radar signal sorting technology,such as based on blind source separation,clustering sorting and based on intra-pulse subtle features are introduced.Meanwhile,the performance fit and unfit quality of these methods are analyzed.Then,the feasibility and advantage of the joint parameters signal sorting and joint algorithms signal sorting are discussed.
