| 摘 要： | 宽带线性调频信号是宽带高分辨率雷达的一种信号形式,在实际应用中可采用Stretch处理来降低A/D采样速率的要求。先推导了系统有误差时线性调频信号Stretch处理的雷达接收回波数学模型,提出误差估计的方法,并针对Stretch处理的时变特性提出了线性调频信号Stretch处理的误差补偿方法。仿真实验表明该方法对宽带线性调频信号误差的估计与补偿是有效的。 |

| Abstract: | Wideband linear frequency modulated signal is a signal form of wideband high resolution radar. It can be processed by using Stretch method, which can decrease the A/D sampling rate in engineering applications. A mathematical model for Stretch processing when the system is imperfect is obtained, the method of error estimation is proposed,and the compensation method based on time-variant property of Stretch processing is also established. Simulation results demonstrate the proposed error estimation and compensation method is effective. |
| Keywords: | wideband radar CHIRP signal Stretch processing error |
