The results of theoretical calculation of spatial correlation functions of bottom clutter on a pair of horizontally arrayed hydrophones are described. Space-cor relation functions are presented for horizontally spread astatic hydrophones and for various spatial arrangements of dipoles relative to one another and relative to the emitted radiation pattern. It is shown that the interference produced by bottom clutter having properties assumed in theoretical limitations can be atten uated by proper selection of the emitted and received radiation pattern.
