| 摘 要： | 在伪码调相连续波引信信号处理部分,相关器输出信号中会包含有动目标的多普勒特性,但这在传统的信号分析中很难体现出来,因此提出对相关器的输出部分展开时空二维联合动态分析,从整体上研究多普勒特性。理论研究发现相关器的输出在空间上为被伪码调相连续波信号的相关函数采样的多普勒信号,相邻采样间隔为码字周期。仿真结果表明了上述结论的正确性,而且从仿真结果图中也很容易观察出在不同时延处相关器输出的多普勒信号,简单易懂。

| Abstract: | The correlator output of pseudorandom code continuous wave ranging fuze contains Doppler characteristics of moving targets,however,it is hard to be reflected in traditional signal analysis.The two-dimensional dynamic simulation analysis of time and space for correlator output was put forward to study the Doppler characteristics.Theoretical analysis found that the correlator outputs were Doppler signals,which was sampled by the correlation function of pseudorandom code phase modulation continuous wave and th... |
