摘要

为解决末制导炮弹转速测量难题,建立了一种基于微多普勒分析的转速测量方法。在对N个翼片形成的多散射中心微多普勒效应分析的基础上,通过对雷达回波进行时频分析,构建极值速度序列。该序列的变化周期是自旋周期的1/N。对极值速度序列进行时域固周测时,变换后可以获得弹丸转速。实际数据处理结果表明,转速和设计值相符。

Abstract

In order to solve the spin-rate measurement problem of the terminal homing projectile, a new method based on micro-Doppler analysis is put forward. Through analyzing the micro-Doppler effect caused by the N wings, multi scatter centers echo model is established. After time-frequency analyzing, the maxim (minim) velocity at every time makes new data. The rotation period is N times of the sequence period. Measure the time of fix periods of the new sequence, then the spin-rate can be calculated. The results show that the outcome of processing the real data accords with the design value.

Key words： terminal homing projectile; micro-Doppler; velocity; spin-rate
