Successful and cost-effective design of an ultrasonic sensor can be problematic. As technological requirements have advanced, sensor complexity has increased dramatically, making intuitive design very difficult. Consequently, new improved models, capable of predicting the device characteristics, are vital for designing complex ultrasonic sensors/systems and keeping pace with the increasingly stringent technological requirements of the future. This book explains how to use a signal processing approach to build effective analytical methods that enable modeling of ultrasonic transduction systems.
