【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.更多还原
