The over-testing problem is mainly caused by the traditional method in which the accelerationspectrum was enveloped and used as the control spectrum of the vibration table.
传统的卫星振动测试由于采用加速度谱包络的方式获取振动台控制谱，导致了“过试验”的发生。

Based on that, a new mode of detection of information about maneuvering target on the basis of range-accelerationspectrum of the improved algorithm is proposed and its rationality is testified.
在此基础上给出了基于改进算法的距离-加速度谱图检测目标机动信息的模式并证明了该检测模式的合理性。
