Micro-Doppler Feature Extraction for Ballistic Missile Warhead

摘要：

To elucidate the spinning signatures of ballistic missile warhead,the model of spinning motion for ballistic missile warhead is established and the mathematical formulas for micro-Doppler signatures caused by spinning motion is derived.Then the time-varying micro-Doppler signatures are analysed with high-resolution time- frequency transform,and the micro-Doppler frequency is calculated based on time-frequency distribution.Finally the computer simulation confirms theoretical analysis, providing theoretical foundation for warheads recognition by micro-Doppler signatures.
