Star Identification

Methods, Techniques and Algorithms

By: Guangjun Zhang

This book summarizes the research advances in star identification that the author’s team has made over the past 10 years, systematically introducing the principles of star identification, general methods, key techniques and practicable algorithms. It also offers examples of hardware implementation and performance evaluation for the star identification algorithms. Star identification is the key step for celestial navigation and greatly improves the performance of star sensors, and as such the book include the fundamentals of star sensors and celestial navigation, the processing of the star catalog and star images, star identification using modified triangle algorithms, star identification using star patterns and using neural networks, rapid star tracking using star matching between adjacent frames, as well as implementation hardware and using performance tests for star identification. It is not only valuable as a reference book for star sensor designers and researchers working in pattern recognition and other related research fields, but also as teaching resource for senior postgraduate and graduate students majoring in information processing, computer science, artificial intelligence, aeronautics and astronautics, automation and instrumentation. Dr. Guangjun Zhang is a professor at the School of Instrumentation Science and Opto-electronics Engineering, Beihang University, China and also the Vice President of Beihang University, China

High-Speed and High-Performance Direct Digital Frequency Synthesizer Design

By: Jun-an Zhang,Ruitao Zhang,Guangjun Li

The book focuses on design technology of high-speed and high-performance direct digital frequency synthesizer (DDS) chip. The technologies involves phase to amplitude converter design, D/A converter design, phase accumulator design, multi-chip synchronization circuit design, etc. In each chapter, the concept of the technology is explained first, and then the features of different implementation schemes are introduced through the real design cases. More over, a design case of a 2.5GHz monolithic DDS in 0.18 μm CMOS which was designed by the authors are introduced in detail, which can help the reader understanding about the of DDS design deeply. The book is suitable for the readers who are interested to learn practical design technology in DDS. The book can benefit researchers, engineers, and graduate students in fields of mix-signal IC design, communication engineering, electronics engineering, and radar engineering, etc.

Earthquake Phenomenology from the Field

The April 20, 2013, Lushan Earthquake

By: Zhongliang Wu,Changsheng Jiang,Xiaojun Li,Guangjun Li,Zhifeng Ding

Based on the field investigation and the summary of the published research results of the April 20, 2013, Lushan, Sichuan, China, MS7.0 earthquake, having occurred along the same fault zone which accommodated the May 12, 2008, Wenchuan MS8.0 earthquake, this Brief tries to describe and discuss the special earthquake phenomenology associated with both the local geology and the changing society. Since the occurrence of this earthquake, there have been the scientific debates on (1) the seismo-tectonics of this earthquake which has no primary seismic fault discovered on the surface of the ground; (2) the relation between this earthquake and the Wenchuan earthquake (i.e., whether it can be considered as one of the aftershocks); and (3) how well have been accomplished in the reduction of earthquake disasters, 5 years after the Wenchuan earthquake. This Brief also tries to introduce the studies and practice of Chinese seismological agencies for the reduction of earthquake disasters. Due to language and cultural barriers, such an introduction makes sense not only for English readers but also for Chinese readers. For example, people (abroad) are always asking why there are so many Chinese seismologists working on earthquake prediction. In fact the Chinese wording 'earthquake prediction' has a much wider coverage than that in English. And actually the Chinese approach to (time-dependent) seismic hazard has no systematic difference from outside world in its methodology.
