摘要： A system for tracking the movement of an object includes a radar device having a first field of view. The radar device generates radar data indicating one of a range corresponding to a distance of a moving object within the first field of view from the radar device and a range rate corresponding to a rate at which the distance is changing relative to the radar device. The system also includes an imager having a second field of view at least partially overlapping the first field of view in an overlap field of view. The imager generates imager data measuring, when the object is in the second field of view, an angular position of the object relative to the imager in at least one dimension. In addition, the system includes a processor combining the radar data and imager data, when the object is in the overlap field of view, to identify a track of the object in at least two dimensions.

摘要： Provided are a sonar device, signal processing method, and recording medium which contribute to improvement in target signal detection ability of an operator. The sonar device comprises a signal detection processing unit and a noise suppression processing unit. The signal detection processing unit calculates a direction vector for each frequency cell and also calculates a resultant vector direction obtained by summing up the direction vectors of all the frequency cells. The noise suppression processing unit calculates, for each frequency cell, the difference between the resultant vector orientation and the signal direction of the frequency cell, and performs a first noise suppression process for suppressing stationary noises included in a received signal such that the noise suppression effect be smaller on a signal of a frequency cell whose signal direction has a smaller difference from the resultant vector direction, and be larger on a signal of a frequency cell whose signal direction has a larger difference from the resultant vector direction.

摘要： A microphone array of three or more microphones may be mounted on a housing or substrate configured to be part of a smartphone or a smartphone protective case. The microphone array may be positioned so that the far field sensing range of the microphone array is unobstructed. The microphone array may be utilized with a beam-forming system in order to determine location of an audio source and a beam-steering system in order to isolate audio emanating from the direction of the audio source. The beam-forming system may be suitable for tracking the movement of one or more audio sources in order to inform the beam-steering system of the direction or location to be isolated.

摘要： A directional audio recording system functions to allow certain audio information to be captured and recorded for later consumption. The selection of audio information for capture may be accomplished by ascertaining the direction of an audio source from a directionally discriminating acoustic sensor and isolating acoustic information originating from the direction so determined. Directional cues may also be recorded and a playback system may apply the directional cues to the stored information representing audio in a spatialization engine such as head-related transfer functions.
