    摘要： A multi-directional sensor may include a microphone array of three or more microphones mounted on a protective headgear. The microphone array may be positioned and configured so that its far field azimuth sensing range is unobstructed by the protective headgear. An accelerometer may be provided and mounted in a location which is fixed with respect to the microphones of the microphone array. A beacon, such as an ultrasonic transmitter or BLE (Bluetooth Low Energy) transmitter may be associated with or attached to the protective headgear. 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 is suitable for tracking the movement of the audio source in order to inform the beam-steering system of the direction or location to be isolated. Because the microphone array will move with a user, a motion sensor may be provided to reduce the computational resources required for tracking and isolation by allowing compensation for change in position and orientation of the user. The beacon will facilitate location of the wearer.

    摘要： A signal processor for processing target echo signal is provided. The signal processor includes a filter configured to generate a filtered echo signal by extracting echo signal components within a predetermined frequency band from the target echo signal, a high resolution signal generator configured to generate a high resolution signal based on the target echo signal, and a synthesizing module configured to synthesize the filtered echo signal with the high resolution signal. The high resolution signal has higher resolution than the filtered echo signal.
