A. K. Bhatia, is a comprehensive guide to the development of radar systems that can be used in various applications such as air traffic control, weather monitoring, navigation, and military surveillance. The book covers all aspects of radar system design, from the principles of operation to the latest advances in technology, including cognitive radar, radar sonar, and navigation systems. The book begins with an introduction to the fundamentals of radar systems, including the principles of electromagnetic waves and their interaction with matter. It then delves into the details of radar system design, including antennas, transmitters, receivers, and signal processing algorithms. The author also discusses the challenges of radar system design, such as interference, multipath effects, and clutter, and provides solutions to mitigate these issues. The second part of the book focuses on cognitive radar systems, which use artificial intelligence and machine learning algorithms to improve the accuracy and reliability of radar systems. The author explains how cognitive radar systems can learn from experience and adapt to changing environments, making them more effective in detecting and tracking targets. The third part of the book covers radar sonar systems, which use sound waves instead of electromagnetic waves to detect objects underwater. The author discusses the advantages and limitations of radar sonar systems and provides examples of their applications in oceanography, fisheries management, and underwater exploration.
