Radar Reflected Signal Process of High Spinning Rate Projectiles

摘要：

By slotting at the bottom of the projectiles, the target characteristics such as the spinning rate and the attitude can be obtained by Doppler radar. The reflection of spin projectile is a nonstationary AM-FM signal. The index of AM represents the attitude of the projectile. And the modulation frequency shows the spinning rate. The model of the reflected waveform is given. Chirp-Z transform (CZT) is adopted to improve the measurement precision. The process approach and the complexity of CZT are present. Its time cost is in the same grade to FFT. Simulation results and perspective are also given.
