This book highlights the application of active array antennas in high-resolution microwave imaging radar systems. It introduces the basic principles, analytical methods, and performance parameters of active array antennas to achieve low profile, high efficiency, and lightweight. The book systematically elaborates the architecture, analysis, and engineering practice to achieve wideband, multi-band, multi-polarization, and common aperture in active array antennas. It explores hotspot technologies of digital array antennas, microwave photonic array antennas, and active packaging antennas. By presenting over 300 illustrations and diagrams, including schematic diagrams, block diagrams, relation diagrams, and breakdown drawings, the book enables a thorough understanding of the antenna array microsystem as the advanced phase of active array antennas and the direction of future R&D. The book is a good reference source for researchers and engineers interested in the engineering and implementation of microwave imaging radar systems and antenna technology.
On the basis of discussing and introducing the basic principles of active array antennas, array synthesis and analysis methods, and modeling techniques for antenna radiation characteristics, this book systematically illustrates the architectures, analysis methods, and engineering practices of active array antennas with the goal of being low profile, high efficiency, and light weight to realize broadband, multi-band, multi-polarization, and shared-aperture properties, and studies digital array antennas, microwave photonic array antennas, active package antennas, and other hot technologies.
This book is divided into 9 chapters. Chapter 1 introduces the characteristics of high-resolution microwave imaging radar and active array antennas, puts forward the new concept of “antenna array microsystems,” and discusses the outlooks of the new technologies and development directions of active array antennas; Chap. 2 analyzes linear arrays, planar arrays, sparse arrays, and beamforming optimization techniques based on the application scenarios by using microwave imaging; Chap. 3 analyzes the influence of active array antenna error factors, introduces antenna measurement techniques, and provides rapid measurement of microwave imaging radar two-dimensional phased array antennas and precise modeling technology; Chap. 4 starts from the mechanism of antenna instantaneous broad bandwidth, analyzes the configuration methods of real-time delay lines, and introduces the design methods and experimental results of common microwave delay components in detail; Chap. 5 focuses on the research of “tile” array modules, miniaturization of chip transceiver components, and three-dimensional heterogeneous integration methods on the basis of discussing the low profile, high efficiency and light weight of active array antennas.
Chap. 6 introduces the requirements and implementation methods of broadband multi-band multi-polarization shared-aperture antennas, focuses on the multi-polarization/multi-band shared-aperture technologies of microstrip patches and waveguide slots antennas, and introduces the triple-band dual-polarization shared-aperture antennas; Chap. 7 analyzes the coupling and mutual interference mechanism of multiple physical quantities at a small scale, studies the parasitic effects between multiple parameters on the basis of introducing the classification of packaged antennas and broadband packaged antenna elements, and explores embedded devices to realize the miniaturization, light weight and high integration of microwave passive devices. Chapter 8 introduces the basic principle of digital array antennas, DDS spectrum characteristic analysis methods, digital signal generation based on DDS spurious suppression, digital sampling, digital down-conversion, and other digital receiving technologies, researches on reducing the noise figure of digital array antenna systems and improving the technical approach to the dynamic range of the system, and proposes a distributed frequency source design idea beyond the traditional frequency synthesizer; Chap. 9 studies and analyzes microwave photonic digital array antennas and optically controlled phased array antennas, and elaborates on the solution to broadband active array antennas. Basic principles and implementation methods of optical real-time delay, microwave signal modulation and demodulation, optical analog-to-digital conversion, and microwave photon filtering.
