This practical textbook introduces the fundamental physics behind radar measurements, to guide students and practitioners in the proper interpretation of radar reflectivity, Doppler velocity and dual-polarization imagery. Operational applications are explored, such as how radar imagery can be used to analyze and forecast convective and widespread weather systems. The book concludes with an overview of current research topics, including the study of clouds and precipitation using radars, signal processing, and data assimilation. Numerous full-color illustrations are included, as well as problem sets, case studies, and a variety of supplementary electronic material including animated time sequences of images to help convey complex concepts. This book is a valuable resource for advanced undergraduate and graduate students in radar meteorology and other related courses, such as precipitation microphysics and dynamics. It will also make a useful reference for researchers, professional meteorologists and hydrologists.

Have you ever wondered how stealth planes achieve "invisibility," how sunken ships are found, or how fishermen track schools of fish in vast expanses of ocean? Radar and sonar echolocation—a simple matter of sending, receiving, and processing signals. Weaving history with simple science, Mark Denny deftly reveals the world of radar and sonar to the curious reader, technology buff, and expert alike. He begins with an early history of the Chain Home radar system used during World War II and then provides accessible and engaging explanations of the physics that make signal processing possible. Basic diagrams and formulas show how electromagnetic and sound waves are transmitted, received, and converted into images, allowing you to literally see in the dark. A section on bioacoustic echolocation, with a focus on the superior sonar systems of bats and whales and a discussion of the advanced technology of next-generation airborne signal processors, opens the imagination to fascinating possibilities for the future.

The Washington Post "[G]randly ambitious... another masterpiece... this genre includes some of the greatest novels of our time, from Pynchon’s V. to David Foster Wallace’s Infinite Jest. That’s the troupe Larsen has decided to join, and I Am Radar is a dazzling performance." The moment just before Radar Radmanovic is born, all of the hospital’s electricity mysteriously fails. The delivery takes place in total darkness. Lights back on, the staff sees a healthy baby boy—with pitch-black skin—born to the stunned white parents. No one understands the uncanny electrical event or the unexpected skin color. “A childbirth is an explosion,” the ancient physician says by way of explanation. “Some shrapnel is inevitable, isn’t it?” A kaleidoscopic novel both heartbreaking and dazzling, Reif Larsen’s I Am Radar begins with Radar’s perplexing birth but rapidly explodes outward, carrying readers across the globe and throughout history, as well as to unknown regions where radio waves and subatomic particles dance to their own design. Spanning this extraordinary range with grace and empathy, humor and courage, I Am Radar is the vessel where a century of conflict and art unite in a mesmerizing narrative whole. Deep in arctic Norway, a cadre of Norwegian schoolteachers is imprisoned during the Second World War. Founding a radical secret society that will hover on the margins of recorded history for decades to come, these schoolteachers steal radioactive material from a hidden Nazi nuclear reactor and use it to stage a surreal art performance on a frozen coastline. This strange society appears again in the aftermath of Cambodia’s murderous Khmer Rouge regime, when another secret performance takes place but goes horrifically wrong. Echoes of this disaster can be heard during the Yugoslavian wars, when an avant-garde puppeteer finds himself trapped inside Belgrade while his brother serves in the genocidal militia that attacks Srebrenica. Decades later, in the war-torn Congo, a disfigured literature professor assembles the largest library in the world even as the country around him collapses. All of these stories are linked by Radar—now a gifted radio operator living in the New Jersey Meadowlands—who struggles with love, a set of hapless parents,and a terrible medical affliction that he has only just begun to comprehend. As I Am Radar accelerates toward its unforgettable conclusion, these divergent strands slowly begin to converge, revealing that beneath our apparent differences, unseen harmonies secretly unite our lives. Drawing on the furthest reaches of quantum physics, forgotten history, and mind-bending art, Larsen’s I Am Radar is a triumph of storytelling at its most primal, elegant, and epic: a breathtaking journey through humanity’s darkest hours only to arrive at a place of shocking wonder and redemption. Cleveland Plain-Dealer "Larsen’s is an extraordinarily lush and verdant imagination, blooming wildly on the borders of the absurd and the riotous, the surreal and the ordinary…Quite unlike any [novel] I’ve read in a long time. One doesn’t consume it; one enters it, as part of a literary enactment… Brilliant…The effort is well-rewarded: It is both maddening and marvelous…I can’t wait to see what he pulls off next."

Recent advances in the study of bats have changed the way we understand this illusive group of mammals. This volume consist of 25 chapters and 57 authors from around the globe all writing on the most recent finding on the evolution, ecology and conservation of bats. The chapters in this book are not intended to be exhaustive literature reviews, but instead extended manuscripts that bring new and fresh perspectives. Many chapters consist of previously unpublished data and are repetitive of new insights and understanding in bat evolution, ecology and conservation. All chapters were peer-reviewed and revised by the authors. Many of the chapters are multi-authored to provide comprehensive and authoritative coverage of the topics.

Since its creation at the beginning of World II, radars have forever transformed the practice of modern warfare. The evolution of countermeasure conducted by electronic warfare systems against radars and radars’ corresponding counter countermeasures is an intriguing technical subject. This book provides a very accessible introduction to a broad range of radar and electronic warfare technologies. The subjects covered in this book range from early radar development to later technologies such as stealthy techniques, low probability of intercept radar, and machine learning. Historical events are used to illustrate the principles of electronic warfare and to help readers to apprehend contexts under which radars and corresponding electronic warfare techniques were developed.
