五象限法声源自动跟踪器

Instrument of sound source automatic tracking using five-quadrant method

介绍由两同心圆组成的等投影面积五象限声 -电测量装置的工作原理 .当声波与声 -电转换器的主要测象限垂直时 ,其声波在主要测象限内产生的声 -电电压最强 .根据声 -电电压的变化大小来确定声源的方向 ,实现自动跟踪 .

The operation principle of a five-quadrant sound-electronic consisting of two concentric circles is introduced. When sound wave is perpendicular to the main measure quadrant of sound-electronic transducer, the most strong sound-electronic voltage will be produced. According to the magnitude of change in sound-electronic voltage, the direction of sound source is detected and the auto matic tracking can be achieved.
