Directivity Pattern of Line Arrays
![]() The directivity pattern of an -element unshaded line array is given by , where , the wave number , is the polar angle, is the steering angle, and is the wavelength. The frequency is Hz and the array inter-element spacing is meters. The wave speed is m/s. In this Demonstration, the inter-element spacing is . You can vary the number of elements in the range 1 to 16, the steering angle in the range -90 to 90 degrees, and the number of points plotted in the azimuthal direction. The array elements are plotted as white dots. ![]() "Directivity Pattern of Line Arrays" from The Wolfram Demonstrations Project http://demonstrations.wolfram.com/DirectivityPatternOfLineArrays/ Contributed by: Christopher Purcell | ||||||||||||||
