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...

Synthesis of Antenna Arrays of Maximum Directivity for a Specified Sidelobe Level

Linear and planar antenna arrays are synthesized to have maximum directivity for a specified sidelobe level. The directivity is maximized subject to a given SLL. The beamwidth and the zeros of array factor are studied as well as the directivity. Maximum directivity-arrays are compared through some examples with super-directive, uniform, Dolph-Chebyshev and Riblet-Chebychev arrays to find a comp...

Modified frame algorithm and its convergence acceleration by Chebyshev method

The aim of this paper is to improve the convergence rate of frame algorithm based on Richardson iteration and Chebyshev methods. Based on Richardson iteration method, we first square the existing convergence rate of frame algorithm which in turn the number of iterations would be bisected and increased speed of convergence is achieved. Afterward, by using Chebyshev polynomials, we improve this s...

Planar Waveguide Arrays for Millimeter Wave Systems

Design of high gain and high efficiency antennas is one of the key challenges in antenna engineering and especially in millimeter wave communication systems. Various types of planar waveguide arrays with series-fed traveling wave operation have been developed in Tokyo Tech with the special focus upon efficiency enhancement as well as reduction of fabrication cost. In this review, four kinds of ...

Design of Linear and Planar Fractal Arrays

This paper describes the theories and techniques for designing linear and planar fractal arrays and compare their radiation pattern with conventional arrays. Fractals are recursively generated object having fractional dimension. We have compared radiation pattern of cantor linear arrays with conventional linear arrays using MATLAB program. Another program was developed to characterize the radia...
