This book presents novel research ideas and offers insights into radar system design, artificial intelligence and signal processing applications. Further, it proposes a new concept of antenna spatial polarization characteristics (SPC), suggesting that the antenna polarization is a function of the spatial direction and providing new ideas for radar signal processing (RSP) and anti-jamming. It also discusses the design of an advanced signal-processing algorithm, and proposes new polarimetric and anti-jamming methods using antenna inherent properties. The book helps readers discover the potential of radar information processing and improve its anti-interference and target identification ability. It is of interest to university researchers, radar engineers and graduate students in computer science and electronics who wish to learn the core principles, methods, algorithms, and applications of RSP.

The emergence of the Internet allows millions of people to use a variety of electronic information retrieval systems, such as: digital libraries, Web search engines, online databases, and online public access catalogs. ""Interactive Information Retrieval in Digital Environments"" provides theoretical framework in understanding the nature of information retrieval, and offers implications for the design and evolution of interactive information retrieval systems. ""Interactive Information Retrieval in Digital Environments"" includes the integration of existing frameworks on user-oriented information retrieval systems across multiple disciplines; the comprehensive review of empirical studies of interactive information retrieval systems for different types of users, tasks, and subtasks; and the discussion of how to evaluate interactive information retrieval systems.Researchers, designers, teachers, scholars, and professionals will gain the foundation for new research on this subject matter, and guidance to evaluate new information retrieval systems for the general public as well as for specific user groups.
