| 摘 要： | 地震台阵的响应特性是衡量台阵对地震监测能力的重要标志。根据台阵响应特性，可分析台阵子台布局的合理性和波数分辨率。本文采用简单延时相加方法，并用不同频率下的波数k为上海地震台阵计算并绘制二维与三维的波数响应图。结果表明，该台阵响应图具有显著的主瓣峰，而且边瓣少且峰值低，具有较高的波数分辨率。

| Abstract: | The response characteristic of seismic array is the important index for estimating the ability of detecting earthquake in the array.According to the response characteristic of array,we can analyze the rationality of array deployment and its wave-number resolution.The wave-number response figures with two-dimension and three-dimension are computed and drawn for Shanghai Seismic Array from wave-numbers(k) with different frequencies by using the method of simple delay-beam.The result shows that the array response figures have the prominent main peak and less sub-peaks with low values,and Shanghai Seismic Array has a higher resolution of wave-number. |
