Optimization design of amplitude weighting for linear phased array acoustic transmitters in acoustic well logging was studied.
对声波测井相控线阵声波辐射器进行了幅度加权的优化设计。
The direction of acoustic beam and angular width of main lobe can be changed by properly amplitude-weighting, decreasing the frequency of impulsive signal and adjusting the interval of array elements.
通过适当的幅度加权、降低激励信号的频率、调整阵元的间距等措施可以改变辐射声束的方向和辐射主瓣的角宽。
The phase and amplitude weighting of the phased array acoustic logging transmitter can be controlled by the two kinds of exciting signal sources.
利用这两种信号源可以对相控线阵声波辐射器进行相位和幅度加权控制。
