University of Electronic Science and Technology of China (UESTC) is a leading university in the domain of information science and technology. It is one of the universities being supported both by the national "211 Project" and co-built by Ministry of Education and the local provincial government. It is also a research-oriented university with its own graduate school. The university has long been reputed as "the cradle of the Chinese national electronic industry". Today UESTC has developed into a multidisciplinary university, which has electronics information science and technology as its nucleus, engineering as its major field, and incorporates science, management and liberal arts. 相似文献

In this paper, the spatial resolutions at different directions of bistatic synthetic aperture radar (BiSAR) have been derived from the ambiguity function. Compared with monostatic signal to noise ratio, BiSAR's resolutions of a fixed point target are varying with slow time since BiSAR system is space-variant. Constraints for the assumption of space-invariant bistatic topology are proposed in the paper. Moreover, under the assumption of invariance, the change of resolutions at different point in the image scene is taken into account, and we have specified two key parameters that affect resolutions directly and analyzed the way how they influence on the resolutions. 相似文献

What will the Post in the world be like in 2005? At first glance, in view of worldwide structural changes, market liberalization and technological development, this question seems very hard to answer. However,without being able to draw a precise picture of the future post services, it can be affirmed that all current providers of postal services will have to face a very different environment from the current one. The objective of this analysis is to contribute to the future development by examining at the worldwide and regional level the major variables influencing the postal industry' s core businesssector, the letter-post, through analyzing the data published by the Universal Postal Union. 相似文献

Based on architecture analysis of island style FPGA,area and delay models of LUT FPGA are proposed.The models are used to analyze the effect of LUT size on FPGA area and performance.Results show optimal LUT size obtained by computation models is the same as that from experiments:a LUT size of 4 produces the best area results,and a LUT size of 5 provides the better performance. 相似文献
