| 摘要: |
| 宽带LFM(线性调频)信号数字脉压中，当采样率不能取得足够高时，在不同的采样率下脉压输出结果将发生变化。此时，采样起点和多普勒频率的变化也将影响脉压结果，并且两者对脉压结果的影响有一定的等效关系。通过较全面的仿真，为宽带LFM信号数字脉压的工程应用中合理选择采样率提供了参考。 |

| The Effect of Sampling Rate on Digital Pulse Compression for Broadband LFM Signals |
|
| () |
| Abstract: |
| The results of digital pulse compression for Broadband LFM signals are influenced by the change of sampling rate especially when the sampling rate cannot be very high. At this time, pulse compression results are influenced by the change of sampling starting point and Doppler frequency, and the influences by them have equivalent relationship. The simulation results in several conditions give references to select reasonable sampling rate in Broadband LFM signal digital pulse compression. |
