SYNTHESIS OF MONOPULSE SUB-ARRAYED LINEAR AND PLANAR ARRAY ANTENNAS WITH OPTIMIZED SIDELOBES

Synthesis of Monopulse Sub-arrayed Linear and Planar Array Antennas with Optimized Sidelobes

In this paper, three approaches for the synthesis of the optimal compromise between sum and difference patterns for subarrayed linear and planar arrays are presented. The synthesis problem is formulated as the definition of the sub-array configuration and the corresponding sub-array weights to minimize the maximum level of the sidelobes of the compromise difference pattern. In the first approac...

Directivity Optimization in Planar Sub-arrayed Monopulse Antenna

In this paper, the Contiguous Partition Method (CPM) is applied to the optimization of the directivity of difference patterns in monopulse planar array antennas. Since the excitations providing maximum directivity of planar arrays can be analytically computed and because of the excitation matching nature of the CPM, the problem at hand is recast as the synthesis of the difference compromise sol...

A Thinning Method of Linear And Planar Array Antennas To Reduce SLL of Radiation Pattern By GWO And ICA Algorithms

In the recent years, the optimization techniques using evolutionary algorithms have been widely used to solve electromagnetic problems. These algorithms use thinning the antenna arrays with the aim of reducing the complexity and thus achieving the optimal solution and decreasing the side lobe level. To obtain the optimal solution, thinning is performed by removing some elements in an array thro...
