Abstract:
PURPOSE: A method for assuming predetermined incidence angle/azimuth angle by using a steering vector is provided to record the predetermined incidence angle/azimuth angle in a recording medium by measuring the predetermined incidence angle/azimuth angle using a steering vector. CONSTITUTION: A steering vector is measured with respect to a first predetermined azimuth angle and a second predetermined incidence angle(200). Then, a dimension of an azimuth angle interpolation is determined(201). If a primary azimuth angle interpolation is selected, two azimuth angles are selected in order to determine an azimuth angle in a direction of the steering vector and a phase of a second incidence angle(202). If a quadratic azimuth angle interpolation is selected, one azimuth angle is selected in order to determine an azimuth angle in a direction of the steering vector and a phase of a second incidence angle. Then, a space spectrum is displayed by assuming the steering vector.
