These keywords were added by machine and not by the authors. Finally the chapter ends with a discussion of biomimetic sonar, which draws inspiration from animals such as bats and dolphins. Various sonar ring designs that provide rapid surrounding environmental coverage are described in conjunction with mapping results. Continuous-transmission frequency-modulated (CTFM) systems are introduced and their ability to improve target sensitivity in the presence of noise is discussed. Sonar systems are described that range in sophistication from low-cost threshold-based ranging modules to multitransducer multipulse configurations with associated signal processing requirements capable of accurate range and bearing measurement, interference rejection, motion compensation, and
Different ultrasonic transducer technologies are outlined with their main characteristics highlighted. The source of sonar artifacts is explained and how they can be dealt with. This chapter presents the fundamentals and physics of sonar sensing for object localization, landmark measurement and classification in robotics applications. Sonar or ultrasonic sensing uses the propagation of acoustic energy at higher frequencies than normal hearing to extract information from the environment.
