This book provides a complete overview of radar system theory and design for consumer applications, from basic short range radar theory to the integration into the real-world products, focusing particularly on gesture sensing in consumer products. It brings you step-by-step through the theoretical understandings, design procedures, analysis tools, and design examples of radar systems.Packed with practical guidance learned from real consumer product development, the book explains how radar works in plain language; provides design principles applied in consumer products; demonstrates algorithms with real world measurement data; describes system trade-offs and cross-functional solutions for solving integration challenges; equips you to design your own radars in consumer electronics for motion sensing and gesture controls.The book focuses on consumer-oriented radar systems with its theory, specifications, application, challenges in integration and co-existence with other radio components. It is self-contained to cover radar hardware, waveforms/modulations, signal processing, detection and classification, machine learning and UX design.With its unique coverage of consumer-oriented radar systems, coupled with the authors’ practical experience in designing radars for today’s consumer products, this is a must-have book for engineers and researchers working with radar systems in consumer electronics and mobile devices such as cell phone, wearables, and in the automotive industry. Downloadable MATLAB(R) scripts and Simulink models are included.
