首先介绍了合成孔径雷达(SAR)的特点，然后阐述了合成孔径雷达原理和末精确制导机制。由于合成孔径雷达能全天候、全天时成像，且采用了合成孔径技术，因此SAR图像不论在距离向，还是方位向均具有高的分辨力，这对发展导弹末段数字式景象相关匹配制导有着重要的意义。-First introduced the synthetic aperture radar (SAR) characteristics, and then expounded the principle of synthetic aperture radar and precision-guided mechanism at the end. As a result of synthetic aperture radar can be all-weather, all the time imaging, and use of synthetic aperture techniques, and that SAR images, whether in the distance to, or position to have a high-resolution, which is the development of the missile in the last paragraph of digital image correlation matching guidance has an important significance.
