| 摘 要： | 反鱼雷鱼雷在浅水工作时,背景混响干扰强,攻击目标具有高速、尺寸小的特点。发射信号应选用高频率、窄脉冲来抗混响干扰。而对高速、小目标的检测,在频域内通过不同多普勒频移将混响与目标区分开来,可降低强混响背景干扰。利用信号在频域的特征可以获得较好的检测效果。 |
| 关 键 词： | 反鱼雷鱼雷 短时傅立叶变换 混响 |

| Abstract: | The anti-torpedo torpedo works in shallow water,where the reverberation plays an important role,and the target is high-speed and small-size,so the beam signal should have high frequency and narrow pulse.For detecting efficiently,high-speed and small-size targets and the reverberation can be differentiated by different frequency shift,which debases interference.These characters in frequency domain help to get better detection effect. |
| Keywords: | anti-torpedo torpedo STFT reverberation |
