| 摘要: |
| 为避免多普勒频移对相位编码信号脉冲压缩处理的影响，提出了利用已知脉冲编码序列对回波信号进行逐符号共轭点乘的脉冲压缩方法，将对齐的回波信号转换为单频信号，并利用傅里叶变换实现信号能量的积累。理论分析与计算机仿真表明，多普勒频移对脉冲压缩性能无影响。该方法适合于应用到对高动态目标进行探测的雷达系统中。 |

| Abstract: |
| This paper proposes a new method of phase coded pulse compression to avoid the effect of Doppler frequency shift.In this method,the echo signal is multiplied with the conjugated known phase code one by one,through which it is transformed to be a monochromatic waveform,and the energy of signal is collected by using Fourier transform.The theoretical analysis and simulation demonstrates that the proposed pulse compression is immune to Doppler frequency shift.Therefore it can be used to detect fast moving targets in radar system. |
| Key words: fast moving target detecting radar phase coded signal pulse compression Doppler frequency shift |
