Inter range cell interference (IRCI)-free synthetic aperture radar (SAR) imaging algorithms
experience antenna-based interference which severely degrades the SAR image. In this …

In this paper, a simple method for null steering is investigated by optimally changing the
locations of the last two edge elements of symmetrical uniformly spaced linear arrays. Unlike …

In this letter, we present an analytical method to design a range-angle-dependent
beampattern using frequency diverse array (FDA) with null depth control (NDC) for joint …

Generally, the null steering is performed by controlling the amplitude and/or phase
weightings of all element excitations or only a small number of them. In such cases, a need …

This paper proposes two methods for multi-wide null steering in the beampattern of
preconfigured partially adaptive planar array antennas using convex optimization and …

Rectangular grid antennas are widely used in practice due to their advantages and
versatility. This paper simplifies the design procedures of such antennas by optimizing their …

In this letter, a fast multinull steering technique is demonstrated by a linearly polarized linear
antenna array. The new technique is based on the electric fields generated by each antenna …

This paper proposes a synthesis and optimization procedure to generate user-specific
shaped and multiple beams in any arbitrary 3D space. The synthesis method generates …

In this paper, the required array patterns with controlled nulls are obtained by optimizing
only the excitation phases of a small number of elements on both sides of the array. A …

This paper presents an effective excitation synthesis algorithm of phased arrays of antennas
to optimize the radiation patterns under minimum mutual coupling/induction interferences …
