PDF-(DOWNLOAD)-Radar Cross Section (Radar, Sonar and Navigation)

This is the second edition of the first and foremost book on this subject for selfstudy training and course work Radar cross section RCS is a comparison of two radar signal strengths One is the strength of the radar beam sweeping over a target the other is the strength of the reflected echo sensed by the receiver This book shows how the RCS gauge can be predicted for theoretical objects and how it can be measured for real targets Predicting RCS is not easy even for simple objects like spheres or cylinders but this book explains the two exact forms of theory so well that even a novice will understand enough to make close predictions Weapons systems developers are keenly interested in reducing the RCS of their platforms The two most practical ways to reduce RCS are shaping and absorption This book explains both in great detail especially in the design evaluation and selection of radar absorbers There is also great detail on the design and employment of indoor and outdoor test ranges for scale models or for fullscale targets such as aircraftIn essence this book covers everything you need to know about RCS from what it is how to predict and measure how to test targets indoors and out and how to beat it.

IceradarObserve ice conditions by radarHybrid ice radarVisualizes ice structures Discovers the optimum route to go through ice Shows the track in bad visibility Usable ice detection up to 4 NM Improv This text and practical reference for all personnel involved in avionics and weapons system evaluation and testing, in the air and on the ground. Compiled from 25 years of experience and methods from the National Test Pilot School in Mojave, California, this book has been reviewed by a dozen voluntary experts from the military and industry to ensure all critical components are properly covered. It includes war stories from actual evaluations and exercises at the end of each chapter, providing instructors with the ability to reinforce critical concepts. This second edition has been updated and expanded by three chapters to include UAV technology, operational test and evaluation and night vision systems and helmet mounted displays and the chapter exercises have also been expanded and revised. Inertial navigation is widely used for the guidance of aircraft, ships, missiles and vehicles. This introduction to the system covers basic principles, system mechanics, instrumentation, computation and design analysis. The text features a particularly contemporary treatment of inertial sensors and computational techniques for error analysis. It also describes integrated systems incorporating additional navigational aids and examples of current applications in both civilian and military situations. This is a comprehensive textbook and reference that provides a solid background in active sensing technology. Beginning with a historical overview and an introductory section on signal generation, filtering and modulation, it follows with a section on radiometry (infrared and microwave) as a background to the active sensing process. The core of the book is concerned with active sensing, starting with the basics of time-of-flight sensors (operational principles, components), and goes through the derivation of the radar range equation, and the detection of echo signals, both fundamental to the understanding of radar, sonar and lidar imaging. Several chapters cover signal propagation of both electromagnetic and acoustic energy, target characteristics, stealth and clutter. The remainder of the book involves the basics of the range measurement process, active imaging with an emphasis on noise and linear frequency modulation techniques, Doppler processing, and target tracking.
