The coarray techniques, e.g., nested and coprime arrays, can significantly improve degrees of freedom (DOFs) via constructing a so-called difference coarray, which enables underdetermined direction-of-arrival (DOA) estimation within reach in the pres

Oblique projection polarization filter (OPPF) can be applied as an effective approach for interference cancellation in high-frequency surface wave radar (HFSWR) and other systems. In order to suppress the nonstationary ionosphere clutter further, a n

In this letter, we consider the problem of underdetermined direction-of-arrival estimation of wideband signals using nested arrays in the framework of sparse signal recovery. The problem is recast into recovering multiple nonnegative sparse signals,

In this letter, we consider the coherent direction-of-arrival estimation problem in impulsive noise. An $\ell _p$ -norm-based variant of the classical relaxation technique is proposed to tackle this problem. The proposed method successively minimizes

This study considers the unimodular sequence train design with low central and recurrent autocorrelation sidelobes. The authors attain the design goal by minimising the integrated energy in central and recurrent autocorrelations with user-supplied we

In shipborne high frequency (HF) hybrid sky-surface wave radar, the sea clutter is the important component of the echoes and the major clutter background for vessel target detection. However, due to the complex radio paths, the sea clutter spectrum s

Acquiring channel state information (CSI) at the base station (BS) is a critical requirement for successfully employing transmit beamforming in multiantenna systems. In practice, channel estimation/quantization errors, feedback delays, and fast fadin
