Abstract

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.
