摘要
“数字信号处理”课程中的分段卷积是来源于工程实践的解决方案,但学生经常对这个知识点的重要性认识不足。文章以PD雷达中对回波信号的脉冲压缩处理为例,介绍什么情况下会出现“N_(1)>>N_(2)”这个分段卷积的前提条件,以及分段卷积在实时信号处理中的工程价值。
Piecewise convolution,in the Digital Signal Processing course,is actually a solution scheme from the engineering practice.However,some students always neglect its importance.A teaching experiment based on the pulse Doppler radar pulse compression is presented in this paper.When and where the precondition‘N_(1)>>N_(2)’in the piecewise convolution would be needed is explained.The engineering value of this precondition in the real-time signal processing is also introduced.
