“…Through this method, it is found that there is an inverse Fourier transform relationship between the array factor and the element excitations. Then, [24] proposed the low-sidelobe pattern synthesis method with nonuniform element spacing, which the idea comes from the NUFFT [25]. The nonuniform distributed elements are firstly converted into a virtual uniform array, then apply FFT to synthesis SLL.…”

Abstract-The pattern synthesis for large antenna arrays has drawn significant attention because of its wide applications. This paper introduces a hybrid approach for the fast pencil beam pattern synthesis of the large non-uniform linear or planar array, which can significantly reduce the computational cost, the number of antenna in the array, the minimum sidelobe level and the null control. The proposed method has an iterative scheme which is composed of the nonuniform Fourier transform (NUFFT) and the global optimization method to minimize the peak sidelobe level and control the null. The NUFFT is utilized to determine excitation magnitudes for a fixed positions non-uniform array. Alternatively, the global optimization is used to find the optimal positions which lead to the minimum peak sidelobe level ( PSL). The lower excitations can be deleted due to yielding less performance on sidelobe level, which is called the array removal strategy. Compare with conventional methods, the simulations on synthetic models show that a minimum sidelobe level and null control can be obtained in processing sparse linear and concentric circular antenna arrays more efficiently.

“…Variety of numerical and analytical methods [7][8][9][10][11][12][13][14][15][16][17][18][19][20] have been introduced for unequally spaced array (USA) pattern synthesis. The first work on USA pattern synthesis was performed by Unz [3] by using a matrix formulation to obtain the distribution of elements current of an USA to form a desired pattern.…”

Abstract-The new numerical model of directional radiation pattern, in which part of energy is emitted in side and back lobs, has been presented in this paper. The model input values are determined on the base of primary parameters that can be read from the datasheet of used antennas. The special software tool NmAntPat has been elaborated to carry out the described task. The elaborated model, program and output files can be easily implemented into an analysis of radio wave propagation phenomenon in any algorithms and numerical calculations. The comparison of the graphical plots that have been obtained on the base of measurements, producers' data specification notes and modelling results confirms the model correctness.
