The identification of warhead and decoys is all the while a technical difficulty of ground-based radar in anti-missile system,while radar identification based on micro-motion performance of ballistic missile targets recently becomes a research hotspot. Micro-Doppler is a kind of representation of target micro-motion performance,and based on differences of micro-motions of warhead and decoys,micro-Doppler signatures can be extracted for target identification. First,Motion performance of warhead and decoys wa...
