چکیده

Circular antenna array design is one of the most important electromagnetic optimization problems of current interest. The antenna must generate a pencil beam pattern in the vertical plane along with minimized side lobe level. In this paper we present non conventional method based on improved parameter of hyper beam exponent x. The circular array when implemented using hyper beam technique, there is a considerable reduction of side lobe levels and half power beam width compared to conventional beam forming. The design of circular array is with uniform inter-element spacing. Simulation results of the effect of the hyper beam exponent on the beam patterns are shown.

Modification of Sidelobe Canceller System In Planar Arrays (RESEARCH NOTE)

A Side Lobe Canceller (SLC) structure is a conventional partially adaptive technique which is used in large adaptive array radars. If a desired signal has long time duration in comparison with the SLC adaptation time, signal components may be cancelled. So, this paper presents a modified SLC which eliminates desired signal cancellation problems and allows using an unconstrained adaptive algorit...

Phase Only Synthesis of Antenna Patterns Using Iterative Restoration Methods

In this work, the method of iterative Fourier transform phase reconstruction, conventionally used in holography and optical image reconstruction, is applied to phase only synthesis of antenna patterns. The method is applied to two types of pattern synthesis problems: "main lobe beam shaping" and "side-lobe-level reduction". The proposed method is most useful in the efficient employment of attai...

An Adaptive Processing of Linear Array for Target Detection Improvement

Antenna arrays yield multiple, simultaneous available beams. These beams can be made to have high gain, low side lobes and controlled beam width. In conventional beam forming, the smallest beam width depends on the geometric dimensions of the receiving array. This problem may overcome by the Hyper beam invention. The linear array when implemented using Hyper beam technique, there is a considera...

Design of Concentric Circular Antenna Array using Biogeography Based Optimization

Biogeography based optimization (BBO) is a novel stochastic force based on the science of biogeography. Biogeography is the schoolwork of geographical allotment of biological organisms. BBO make use of migration operator to share information between the problem solutions. The problem solutions are called as habitats and sharing of features is called migration. In this paper, BBO algorithm is de...
