| 摘要: |
| 本文论述了采用FFT技术进行弹丸速度测定。这种技术优于传统的模拟滤波器，可以同时测定位于天线波束内的多个弹丸的速度；经数字滤波器过滤后的信号具有更高的信杂比和信噪比，从而测速距离有较大的提高。仿真表明，应用FFT技术测速，也有较高的精度。 |

| Abstract: |
| The paper discusses the technology of speed measurement of projectiles with FFT method. This method is superior to that of the traditional analog filter speed measurement. It can measure the speeds of many projectiles in the antenna. The signal，which was filtered by the digital filter，has higher signal-to-clutter ratio and noise ratio. Thus，the distance of measuring speed can be increased greatly. The simulation results show that the higher accuracy can be obtained by using FFT technology. |
