    • A hybrid acoustic sensor can include a first acoustic sensor, a second acoustic sensor, and a mixer. The first acoustic sensor can generate a first signal to represent acoustic data in a first bandwidth around a first center frequency. The second acoustic sensor can be co-located with the first acoustic sensor, and can generate a second signal to represent the acoustic data in a second bandwidth around a second center frequency. A lower bound of the first bandwidth can be at a lower frequency than a lower bound of the second bandwidth, and a higher bound of the second bandwidth can be at a higher frequency than a higher bound of the first bandwidth. The mixer can combine the first signal and the second signal into a third signal to represent the acoustic data in a third bandwidth from the lower frequency to the higher frequency.
    • 混合声学传感器可以包括第一声学传感器,第二声学传感器和混合器。 第一声​​传感器可以产生第一信号以在围绕第一中心频率的第一带宽中表示声学数据。 第二声传感器可以与第一声传感器共定位,并且可以产生第二信号以在围绕第二中心频率的第二带宽中表示声学数据。 第一带宽的下限可以处于比第二带宽的下限更低的频率,并且第二带宽的较高边界可以处于比第一带宽的较高边界更高的频率。 混频器可以将第一信号和第二信号组合成第三信号,以在从较低频率到较高频率的第三带宽中表示声学数据。

    • In one embodiment, a tracking module (110) to select a plurality of pairs of digital ultrasonic signals to form two or more pairs of digital ultrasonic signals and estimate time difference of arrival (TDOA) for each of the two or more pairs of digital ultrasonic signals. The tracking module (110) may further determine an intersection of each pair of the TDOA estimated digital ultrasonic signals to form one or more intersections and a location of an ultrasonic signal generator (102) corresponding to at least one of the one or more intersections.
    • 在一个实施例中,跟踪模块(110)选择多对数字超声波信号以形成两对或更多对数字超声波信号,并估计两对或更多对数字超声波中的每一对的时间到达差(TDOA) 信号。 跟踪模块(110)还可以确定每对TDOA估计的数字超声波信号的交点以形成对应于一个或多个交叉点中的至少一个的一个或多个交叉点和超声信号发生器(102)的位置。
