    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.
