摘要

摘要: 线性调频信号具有抗干扰和对抗能力强等优点, 广泛应用于雷达、通信和鱼雷自导等领域, 但对于鱼雷电磁引信还属于一种新的信号体制。文中建立了鱼雷电磁引信模型, 阐述了线性调频信号的工作原理,研究了线性调频信号的产生, 分析了回波信号的幅频特性。通过MATLAB软件对其抗干扰性能进行仿真, 验证了线性调频信号作为鱼雷主动电磁引信探测信号的可行性。

Abstract: Linear frequency modulation(LFM) signal has the advantages of anti-interference and strong resistance, so it has been widely used in radar, communication and torpedo homing. However LMF is a new signal system to torpedo electromagnetic fuze. In this paper, an electromagnetic fuze model of a torpedo is established, the working principle of LFM signal is expounded, the generation of LFM signal is investigated, and the amplitude frequency characteristic of echo signal is analyzed. The software MATLAB is adopted to simulate the anti-interference performance of LFM signal, and the results show that LFM signal can be applied to detection of torpedo active electromagnetic fuze.
