A self-contained approach to DSP techniques and applications in radar imaging
The processing of radar images, in general, consists of three major fields: Digital Signal Processing (DSP); antenna and radar operation; and algorithms used to process the radar images. This book brings together material from these different areas to allow readers to gain a thorough understanding of how radar images are processed.
The book is divided into three main parts and covers:

* DSP principles and signal characteristics in both analog and digital domains, advanced signal sampling, and interpolation techniques
*
Antenna theory (Maxwell equation, radiation field from dipole, and linear phased array), radar fundamentals, radar modulation, and target-detection techniques (continuous wave, pulsed Linear Frequency Modulation, and stepped Frequency Modulation)
*
Properties of radar images, algorithms used for radar image processing, simulation examples, and results of satellite image files processed by Range-Doppler and Stolt interpolation algorithms

The book fully utilizes the computing and graphical capability of MATLAB? to display the signals at various processing stages in 3D and/or cross-sectional views. Additionally, the text is complemented with flowcharts and system block diagrams to aid in readers' comprehension.
Digital Signal Processing Techniques and Applications in Radar Image Processing serves as an ideal textbook for graduate students and practicing engineers who wish to gain firsthand experience in applying DSP principles and technologies to radar imaging.

This book provides a comprehensive and systematic framework for the design of adaptive architectures, which take advantage of the available a priori information to enhance the detection performance. Moreover, this framework also provides guidelines to develop decision schemes capable of estimating the target position within the range bin. To this end, the readers are driven step-by-step towards those aspects that have to be accounted for at the design stage, starting from the exploitation of system and/or environment information up to the use of target energy leakage (energy spillover), which allows inferring on the target position within the range cell under test.In addition to design issues, this book presents an extensive number of illustrative examples based upon both simulated and real-recorded data. Moreover, the performance analysis is enriched by considerations about the trade-off between performances and computational requirements.Finally, this book could be a valuable resource for PhD students, researchers, professors, and, more generally, engineers working on statistical signal processing and its applications to radar systems.

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.

For all radar users, recreational and professional. Covers the use of radar for chart navigation, blind pilotage, and collision avoidance. This Workbook is designed to be used in classroom or online courses in radar, or for individual study outside of the classroom. The lesson structure follows that used by several schools in the US, based on the background reader Radar for Mariners by David Burch. The Appendix on advanced radar plotting is included for professional mariners who seek more practice on interpreting ARPA output by working out the vector solutions themselves. The ability to manually interpret the radar interactions seen on the screen, independent of electronic solutions, is in keeping with the fundamental tenet of good navigation and seamanship that we should not rely on any one aid alone.

During the 1930s the popular press were carrying stories of a death ray that could disable aircraft, and it became such a popular notion that an investigation was carried out by a government scientist, Robert Watson-Watt. His discovery was that it was not that electro-magnetic waves could interfere with aircraft, but that aircraft could interfere with radio transmissions. The strategic importance of this was appreciated and a secret establishment was set up to develop a means of using radio transmissions to detect the approach of enemy aircraft - the birth of radar. As World War II broke out Ian Goult joined this elite group of scientists - aged only sixteen - as a lab assistant, working on GEE, a navigational aid allowing accurate location of targets. Its success allowed Bomber command to effectively navigate as far as the Ruhr. In Secret Location, Goult describes taking part in work on radar and microwave techniques that gave Britain supremacy in the air, and greatly improved submarine detection during the Battle of the Atlantic, saving thousands of tons of materiel and many lives. Told in an engaging style, this book offers a unique insight in those men whose achievements during the war have been underappreciated, but whose efforts were a key factor in the Allied victory. Postwar, Ian Goult was closely involved in the development of ground proximity warning systems and and the very first ATOL.
