摘　　要：为了降低多通道信号的时间不确定性,提出一种信号的时间轴校准方法,在校准环节确定校准系数,采用插值法校准信号,在不增加硬件成本、仅增加有限的软件资源消耗,用软件算法进行时间轴的校准,降低了时间不确定性的影响,提高了信号的准确度,保证了电子系统数据融合的有效性。In order to reduce the time uncertainty of multi-channel signals, a calibration method of signal time axis is proposed in this paper. The calibration coefficient is determined in the calibration step, and the interpolation method is used to calibrate the signals. Without increasing the hardware cost and only increasing the limited software resources, the software algorithm is used to calibrate the time axis, which reduces the influence of time uncertainty and improves the accuracy of the signal, it ensures the effectiveness of electronic system information fusion.
