当处理声学数据时，通常期望产生根据标准物理单位（诸如微帕斯卡）校准的结果。本文导出了DIFAR声纳浮标数据定标所需的几个定标因子。这些因素是声纳浮标的全向和偶极传感器的声学灵敏度，当浮标处于已知强度的声压场中时，由飞机无线电接收机输出端的电压电平定义。
When processing acoustic data, it is often desired to produce results that are calibrated in terms of standard physical units, such as micropascals. In this note, several scaling factors needed for calibrating DIFAR sonobuoy data are derived. These factors are the acoustic sensitivities of the omni-directional and dipole sensors of the sonobuoy, as defined by the voltage levels at the output of the aircraft radio receiver when the buoy is in an acoustic pressure field of known intensity.
