We design a grey wolf optimizer hybridized with an interior point algorithm to correct a faulty
antenna array. If a single sensor fails, the radiation power pattern of the entire array is …

In this paper, we propose a novel technique that integrates the detection of element failures
and the correction of damaged patterns into a systematic process for active phased arrays …

Because the possibility of array element failure during operation cannot be ruled out [1],
selfrecoverable antenna array systems have recently been receiving considerable attention …

The defective array elements which are unavoidable due to the long full-time antenna
system operation directly affect its radiation pattern, sidelobe level (SLL), directivity, and the …

In this article, a convex optimization method for failure correction of impaired antenna arrays
is proposed. The number of elements to be corrected is iteratively minimized through the …

This paper proposes the correction of faulty sensors using a synthesis of the greedy sparse
constrained optimization GSCO) technique. The failure of sensors can damage the radiation …

In this paper, a novel approach for simultaneously correcting multiple degraded patterns
under the failure condition of time-modulated linear arrays is proposed. The approach is …

An antenna array element failure problem is one of the practical and challenging issues in
the field of adaptive beamforming. The complete radiation pattern of the array is distorted …

In this paper, multi-objective particle swarm optimization (MOPSO) and continuous excitation
distribution in the range of 0 to 2 are used for correction of the failed element in 5× 5 planar …

Over a decade, the evolutionary and social inspired computing techniques have
revolutionarised the nonlinear problem-solving methods with their efficiency in searching for …
