In seismic data acquisition, source and receiver array is used for attenuation of surface waves caused by the source. To further attenuate surface waves it necessary to optimize arrays.
One of the ways to optimize source and receiver arrays is spatial convolution. In this method each complex array consists of several simple arrays which make a large array when joined together. By using simple arrays of 2 and 3 elements and putting notch points of these arrays in side lobes of the final response of the array, the side lobes can be reduced.
