Abstract Modulation recognition of single‐component radar signals has been widely studied in the fewer years. Meanwhile, as the electromagnetic environment in the actual battlefields is ever‐increasingly complicated, the demand for the modulation

Abstract In bearings-only localization, clustering-based methods have been widely used to remove spurious intersections by fusing multiple bearing measurements from different observation stations. Existing clustering methods, including fuzzy C-mean (

Abstract The electromagnetic environment of modern battlefields becomes increasingly complex, and radar receivers may receive multiple radar signals simultaneously. However, current deep learning models can only predict a single class and cannot reco

To address the problem that traditional direction-of-arrival (DOA) estimation algorithms did not fully utilize the signal characteristics of active decoys and radar, which led to poor angular resolution of anti-radiation missile, a single sna

In this paper, a novel method based on multiple matrix reconstruction without eigen decomposition is proposed for solving the problem of two-dimensional (2-D) direction-of-arrival (DOA) estimation of mixed signals impinging on a planar array composin

This paper proposes a novel estimation method, named double scale two dimensional frequency distribution (DSTFD), to estimate the parameters of quadratic frequency modulated (QFM) signals. In the DSTFD, by using a novel parametric instantaneous self-

Co-prime array configurations are considered attractive due to the extension of degrees of freedom (DOFs) and the sparse placement of array elements. In this paper, a 2-D direction-of-arrival (DOA) and polarization estimation algorithm are proposed w

As is well known, the prototype coprime arrays consist of two collinear subarrays, whose physical sensor number is coprime to each other. Moreover, their larger inter-element separations and physical array apertures make them have less mutual couplin
