文中给出了计算单个震源方向特性的一般组合理论。组合震源的频率-方向特性等于单个震源的频率-方向特性乘以点阵的频率-方向特性。利用相控组合可以获得定向波束,有助于研究复杂的地质构造。文中还给出了计算相移的公式。
In this paper, a general combinatorial theory for calculating the directional characteristics of a single source is given. The frequency-direction characteristics of the combined source are equal to the frequency-direction characteristics of a single source multiplied by the frequency-direction characteristics of the lattice. The use of phased array can be obtained directional beam, help to study complex geological structure. The paper also gives the formula to calculate the phase shift.
