一种基于系数截断的矩阵束算法的信号合成技术

A Signal Synthesis Technology Using Coefficient Truncation Based Matrix Pencil Algorithm

本文研究了基于系数截断的矩阵束算法建立散射点回波模型,继而计算相位相干量和幅度相干量,然后完成双频段回波信号相干配准,把独立工作在不同频段的两个子带信号合成在一起以达到增加带宽的目的。经仿真和工程验证,该方法可行有效。

In this paper,a scattering point echo model is established using the coefficient truncation based matrix pencil algorithm.Then,the phase coherence and amplitude coherence are calculated.Finally,the coherent registration of dual-band echo signals is performed to combine two signals that work independently in different frequency bands,thus increasing the signal bandwidth.The simulation and engineering test results show that the proposed method is feasible and effective.
