| 摘 要： | 相位编码信号对多普勒敏感,不能很好地实现脉冲压缩。在分析多普勒失配对相位编码信号脉压影响的基础上提出一种多普勒补偿的方法来实现脉压,这种方法很好地解决了相位编码信号对多普勒的敏感性。通过在某雷达信号处理机实际工程中的应用表明:该方法算法实现简单,脉压性能好,完全能满足工程应用的要求。

| Abstract: | Codes used in phase-coded pulse compression waveforms suffer from Doppler mismatch.Based on an analysis of the effects of doppler mismatch on quariphase-coded waveforms and the performance results,a new technique of doppler compensation is proposed.This technique solves the problem of the sensitivity of phase-coded signal to Doppler.It is proved that pulse compression performance is quite well by using this simple technique,and it meets the project's requirement very well. |

| Keywords: | phase-coded signal pulse compression Doppler velocity compensation |
