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.
