Abstract : A new approach to the array problem is shown which is particularly suited for unequally spaced arrays with a large number of elements which may be located on a line or on a curve. It is shown that an unequally spaced array of uniform amplitude with any desired sidelobe level may be designed using our method. Also, the secondary beam suppression and the azimuth frequency scanning circular array was discussed to show the effectiveness of the method. Other applications including unequally spaced array on a travelling wave waveguide, the amplitude modulated antennas, the leaky-wave antennas, and the frequency scanning linear antennas are discussed.
