介绍了麦克风阵列相控阵波束形成技术。波束形成从时域和频域两个方面考虑。传统的波束形成技术被处理，但也更先进的技术。特别注意移动源的定位。展示了风洞测量和飞机立交桥测量的应用。
An introduction is given of phased array beamforming with microphone arrays. Beamforming is considered both in the time-domain and in the frequency-domain. Conventional beamforming techniques are treated, but also more advanced techniques. Special attention is paid to the localisation of moving sources. Applications are shown of wind tunnel measurements and aircraft flyover measurements.
