然后，从弹载高重频脉冲多普勒雷达的多普勒分辨率和加速度分辨率出发，结合不同编队方式的多目标回波信号的特点，分析了多目标和单个目标的回波信号的多普勒谱和加速度谱的特性，提出了一种基于一维多普勒像和一维加速度像的级次多目标分辨算法。 - Based on frequency - spectrum - transformation , this algorithm first changes acceleration spectrum into displacement spectrum , then calculates its amplitude , angular frequency and initial angle related to every displacement spectrum , finally sums up all the displacement components and forms the time course of the measured vibration
该方法采用频谱转换法，首先将加速度谱转换成位移谱，再计算出位移谱中每个频率分量对应的幅值、圆频率和初相角，最后对各位移分量进行叠加得到振动位移的时间历程。
