| 摘 要： | 调频连续波合成孔径雷达(FMCW SAR)是一种新近提出来的成像雷达体制,在FMCW SAR成像中,相位误差是成像质量下降的主要原因,必须对相位误差进行消除.首先建立了存在二次相位误差的FMCW SAR的信号模型,然后分析了二次相位误差对成像质量的影响,提出了一种补偿二次相位误差的方法.此方法与存在二次相位误差时的成像结果相比较,有效地消除了二次相位误差的影响,成像质量大为提高.

| Abstract: | Frequency modulated continuous wave (FMCW) synthetic aperture radar (SAR) is a newly proposed imaging radar system. The phase errors are the prime reasons which result in the deteriorative imaging quality during the image for FMCW SAR. The effect of phase errors should be eliminated. Firstly the signal model of FMCW SAR which includes the secondary phase error is established. Then the influence of secondary phase error to FMCW SAR image Quality is analyzed. And based on this, this paper brings forward a com... |
