| 摘 要： | 分析了鱼雷电磁引信的目标信号及其低频调制包络的特性,阐述了Hilbert变换的原理,提出了一种基于Hilbert变换的包络解调法并对其解调原理进行了推导.在Matlab/Simulink环境下,对上述的包络解调法应用于电磁引信目标信号的解调进行了仿真.结果表明,相比传统的电磁引信检波方法,Hilbert 变换法具有解调输出信号波形失真小和解调稳定性高的优点.

| Abstract: | The target signal of torpedo electromagnetic fuze and the characteristics of its demodulated envelope were analyzed;the principle of Hilbert transformation was expounded;an envelope demodulation method based on Hilbert transformation was proposed,and its demodulation principle was deduced.By Matlab/Simulink software,the simulation of the above method was conducted for demodulating the electromagnetic fuze target signal.The results show that,compared with traditional methods,the Hilbert transform method has ... |
