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. 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
