A detailed treatment of antenna system noise, sections on antenna pattern synthesis, developments in subarray technology, and in-depth information on array architecture and components are also new features of this book. This book provides complete design details that demonstrate how to size an array system with speed and confidence. Moreover, this book provides expanded coverage of systems aspects of arrays for radar and communications. Supported with numerous equations and illustrations, this practical book helps evaluate basic antenna parameters such as gain, sidelobe levels, and noise. Readers learn how to compute antenna system noise, design subarray geometries for given bandwidth, scan and sidelobe constraints, and choose array illumination tapers for given sidelobe levels
