Abstract：The paper systematically discussed the theoretical problem of receiver array and shot receiver array in special surface conditions.We acknowl edged by theoretical study and field test that in a condition of complicated surface (inclined or relief surface) the passband of directional characteristic curve of the array becomes broaden and the average of suppression band increases when the elevation difference (Δh) between adjacent receivers increases,which degrades suppression effect on surface wave having lower apparent velocity,but there is no obvious change in directional character of the array when elevation difference (Δh) of incline surface is less than 4m;linear array with unequal sensitivity is more favorable for suppression of surface wave having lower apparent velocity;areal pattern can suppress surface wave with any propagation direction and parallelogram's pattern is superior to rectangular pattern,which the former has more broad suppressed band and severe amplitude suppression;comparison of array characters between the impulse and simple harmonic wave resulted in both having consistent passband width but the former having non periodic suppression band,which its amplitude oscillates on 1/n.
