The Micro-doppler Effect in Radar

The Doppler Effect can be thought of as the change in frequency of a wave for an observer moving relative to the source of the wave. In radar, it is used to measure the velocity of detected objects. This highly practical resource provides thorough working knowledge of the micro-Doppler effect in radar, including its principles, applications and implementation with MATLAB codes. The book presents code for simulating radar backscattering from targets with various motions, generating micro-Doppler signatures, and analyzing the characteristics of targets. In this title, professionals will find detailed descriptions of the physics and mathematics of the Doppler and micro-Doppler effect. The book provides a wide range of clear examples, including an oscillating pendulum, a spinning and precession heavy top, rotating rotor blades of a helicopter, rotating wind-turbine blades, a person walking with swinging arms and legs, a flying bird, and movements of quadruped animals.

  • Publisher: IET

There is a growing interest in how to use radar micro-Doppler signatures in real world applications. This book introduces basic concepts, principles, and theoretical analysis on the micro-Doppler effect in radar and pulls together the latest research on the processing and application of radar micro-Doppler signatures. Its goal is to provide readers with a working knowledge on various applications of radar micro-Doppler signatures. It reviews the current progress, challenges, and perspectives on radar micro-Doppler research and introduces research on bi-static/multi-static micro-Doppler signatures, decomposition of micro-Doppler signatures, through-wall radar micro-Doppler signatures and ultrasound micro-Doppler signature studies. Most chapters deal with applications of radar micro-Doppler signatures, including detection, tracking and discrimination of vehicles and dismounts, identifying human movement based on radar micro-Doppler signatures, detection and tracking small boats in the sea, detection and discrimination complex motion of missile warheads, discrimination of animals and the detection and tracking of birds.

Cut Loose

"Years after the Great Recession, the economy is still weak, and an unprecedented number of workers have sunk into long spells of unemployment, increasingly unlikely to get another good job in their lifetimes. Based on a careful crossnational comparison, "Cut Loose" describes the experiences of American and Canadian unemployed workers and the impact of the different social policies meant to help them. It focuses on a historically important group: autoworkers. Their well-paid factory jobs built a strong middle class in the decades after World War II. But today, they find themselves lost and beleaguered in a changed economy of greater inequality and risk, one that favors the well-educated--or ...

Through-the-wall radar imaging (TWRI) allows police, fire and rescue personnel, first responders, and defense forces to detect, identify, classify, and track the whereabouts of humans and moving objects. Electromagnetic waves are considered the most effective at achieving this objective, yet advances in this multi-faceted and multi-disciplinary technology require taking phenomenological issues into consideration and must be based on a solid understanding of the intricacies of EM wave interactions with interior and exterior objects and structures. Providing a broad overview of the myriad factors involved, namely size, weight, mobility, acquisition time, aperture distribution, power, bandwidth...

  • Publisher: Artech House

This multimedia eBook establishes a solid foundation in the essential principles of how signals interact with transmission lines, how the physical design of interconnects affects transmission line properties, and how to interpret single-ended and differential time domain reflection (TDR) measurements to extract important figures of merits and avoid common mistakes. This book presents an intuitive understanding of transmission lines. Instructional videos are provided in every chapter that cover important aspects of the interconnect design and characterization process. This video eBook helps establish foundations for designing and characterizing the electrical properties of interconnects to explain in a simplified way how signals propagate and interact with interconnects and how the physical design of transmission structures will impact performance. Never be intimidated by impedance or differential pairs again.

Calcium

Calcium's importance in health and disease is clear when listing its multiple roles in the body, which include building strong bones and teeth, vascular calcification, muscle function, hormonal regulation and maintaining a normal heartbeat. This book will examine these roles and will also cover areas such as chemical analysis, sources of calcium based on geography, influence of Vitamin D, hypercalcemia and the effects of dietary calcium. This edited volume will pool knowledge across scientific disciplines in a way that increases its applicability to a wide range of audiences and fills the gap identified in providing comprehensive synopses of food substances. Chemists, analytical scientists, forensic scientists, food scientists, as well as course lecturers and university librarians, will all benefit from this title.
