| 摘 要： | 带宽不够、波形易失真是纳秒级脉冲信号测量中存在的主要问题.以测量系统的方波标定数据为标准建立测量系统的差分方程和卷积两种模型，并分别运用于实际试验的双指数脉冲信号的波形预测和重构中，对比两种模型的信号处理结果发现，卷积模型比差分方程模型更适用于纳秒级脉冲信号的波形预测和重构.

| Abstract: | The main problem in nanosecond pulse signal measurement is narrow bandwidth and distorted waveform.Based on the square wave calibration data of the measurement system,a difference equation model and a convolution model of the measurement system are established,which are used in the actual test of the double exponential pulse waveform prediction and reconstruction for signal processing.Model results show that the convolution model is more suitable than differential equation model in the nanosecond pulse waveform prediction and reconstruction. |

| Keywords: | pulse signal processing differential equation convolution |
