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.

Discussing embedded systems in general is difficult, because each embedded system is unique. Rather than presenting a list of general principles for handling embedded development issues, this book presents examples of problems encountered and solutions to those problems using real hardware and software. In that sense, it is a “cookbook” for developers that offers design “recipes” that can be elaborated on or modified as needed to solve other design problems.

Welcome to PMOS. PMOS is a set of modules, mostly written in Modula-2, to support multitasking. PMOS was designed primarily with real-time applications in mind. It is not an operating system in the conventional sense rather, it is a collection of modules which you can import into your own programs, and which in particular allow you to write multi-threaded programs. -Welcome to PMOS.
