Array Gain Analysis of Uniform Circular Array Mounted on A Cylinder

摘要：

　　The array gain and array supergain of a uniform circular array (UCA) under different circumstances is studied based on the array model of a UCA mounted on a cylinder.The algebraic expressions of the array gain and array supergain are derived.The variety of the array gain and array supergain under different circumstances is compared by computer simulations.Simulation results demonstrate that the cylinder can improve the array gain and array supergain.When the UCA mounted on an air-coupled cylinder,the array gain and array supergain can be improved further in special frequency band by setting the impedance properly.The offset between the array and the cylinder can reduce the array gain to a certain extent.
