Antenna arrays with shaped power patterns have many applications in communications and radars. Many antenna array synthesis techniques for shaped patterns have been developed in the past years, and most of them deal only with uniformly spaced arrays. In this paper, a new method is proposed for the synthesis of nonuniform linear antenna arrays with shaped power patterns. The proposed synthesis method consists of three steps. First, we flnd a satisfactory power pattern for the required radiation characteristics by solving a constrained least-squares problem which is obtained with the help of non-redundant representation of squared magnitude of a linear array factor. Then, we factorize the polynomial associated with the power pattern by using polynomial rooting, and consequently obtain the corresponding fleld patterns. Finally, the forward-backward matrix pencil method is used to obtain a nonuniform linear array with optimized excitation magnitudes, phases and locations for a speciflc choice of fleld patterns. The synthesized array has a smaller number of elements than the one with uniformly spaced elements for the same

• Synthesis of Sparse Arrays With Focused or Shaped Beampattern via Sequential Convex Optimizations (2012, methodology): “3(b),(c), the results of the FBMPM are similar to those obtained applying our method, where only the shaped beam is discretized and the sidelobes are upper bounded, as formulated in (11).”
• Maximally Sparse Arrays Via Sequential Convex Optimizations (2012, unknown): “Furthermore, regarding the reference field to a set achieved by arbitrarily fixing the sensor positions (equally spaced half-wavelength array; see [5] and [6]), there is no guarantee that the number of antennas of the resulting array is the minimum one.”
