—This paper presents a reflector recognition and local-ization technique in three-dimensional (3-D) environments, using only times-of-flight (TOFs) data obtained from ultrasonic transducers. The recognition and localization technique is based on the principal component analysis applied to the TOF vectors originating from a sensor that contains two emitting(More)
Complementary sequences are being employed to improve the results obtained in many sensorial systems where it is necessary to enhance the signal to noise ratio imposed by the environment. This improvement is achieved at the expense of increasing the computational complexity of the signal processing tasks. This work presents the hardware implementation of an(More)
An advanced adaptive sonar module is described, capable of being configured to different circumstances and distances according to reflectors found in the environment. Thanks to the sensory distribution, it is possible to identify three basic types of reflector (planes, edges and corners). Furthermore, a heuristic map of the environment is built. The(More)
