Примери за sonar

• Often they use sonar to look for sunken ships on the sea floor. 

• In particular, the book is aimed at signal processing practitioners, especially research workers and students working in areas of radar, sonar, telecommunications and biomedical engineering.

• Each receiver of advanced sonar ring localizes multiple targets on one firing.

• Each sonar transmits a number of pulses fired in sequence, the exact number of which is determined by a unique code.

• The mobile robots may navigate by means of a number of monitoring systems such as the sonar-sensing system or the visual-sensing system.

• This procedure makes use of past sonar readings stored in the occupancy grid map.

• Side-scan sonar and seismic methods have been used widely to map these topographic structures.

• Observations are made using an imaging sonar that scans the horizontal plane around the vehicle.

• They include, for example, mappings of two- or three-dimensional images such as portraits or underwater sonar scans into other images for comparison.

• Many commercially available mobile platforms already have integrated sonar sensors for the detection of obstacles around the platform.

• Only integrated sonar sensor were used for obstacle detection.

• These were very expensive items: radar, sonar, radio transmitters and receivers-large, expensive equipment, sometimes worth half a million 1955 dollars for each item.

• The program computes the time of flight and the sonar that has received the echo.

• Individual sonar returns are marked by a dot.

• The sonar principal returns have been plotted relative to the estimated position of the vehicle.

• The interface has different robotic components, such as drive functions, sonar, laser, odometer, and camera.
