SciTech publishing has recently released a new book, Introduction to Adaptive Arrays, 2nd Edition, by Robert A. Monzingo, Randy Haupt, Thomas W. Miller, which addresses the subject of adaptive array sensor systems. I asked them for an excerpt for our site, and they provided a PDF of Chapter 2, which I have divided into two parts due to size. If you would like to see the complete table of contents or would like to order the book, head on over to the SciTech website for more information.
Chapter 2, excerpted in this series of articles, introduces the adaptive array concept by first looking at the effects of the signal environment and then moving on to array architecture. This chapter also demonstrates how to enhance the output SNR performance by adjusting the beamforming network.
Chapter 3 introduces several widely used performance measures for narrowband and broadband applications. Part II of the book, which is made up of Chapters 4 through 8, introduces different classes of adaptation algorithms. Each chapter has problems at the end, making it suitable for classroom use.
We will present Chapter 2 in two parts. Part 1 covers signal environment, element spacing considerations, and array performance. Part 2 covers nulling limitations, narrowband/broadband considerations, and performance measure.
