摘要： 通过分析低轨空间目标的姿态运动对窄带回波脉冲数据的调制,表明低轨空间目标窄带回波脉冲数据信号的相位比幅度包含了更多的目标特征信息。采用小波分析从实测窄带相参回波特性数据的相位中,估计低轨空间目标的整体运动趋势,判别低轨空间目标的粗略类型,并通过大量实测数据的实验结果验证了该方法判别低轨空间目标粗略类型的有效性。

Abstract: The low orbit space object's attitude movement's modulation to narrow-band echo(impulse) signal is analyzed.It shows that low orbit space object's narrowband signal's phase contains much more important features than its magnitude.Wavelet is applied to detect long-term evolution of the movement from the phase of narrow-band signal and to identify the low orbit space object's sketchy types.Experimentation with a great deal of real measured data proves that it be useful in(identifying) the low orbit space object's sketchy types.
