A method to measure horizontal and vertical polar patterns of large arrays under actual free-field conditions is described. Ways in which the polar patterns of large arrays deviate from a theoretical model of a curved-surface source are discussed; thus the term arrayability is introduced. Criteria for arrayability are suggested.
