Abstract :
A direction-finding technique is developed which uses the outputs of a virtual array computed from the real array using a linear interpolation procedure. The geometry of the virtual array is under the control of the designer. Using a linear virtual array, an extension of the root-MUSIC algorithm to arbitrary array geometries is developed
