This paper introduces a novel direction-of-arrival (DOA) estimation method for the closely
related wideband sources. The new method estimates the DOAs accurately by evaluating …

In complex multipath environments, accurate direction of arrival (DOA) estimation for
wideband signal and effectively separating the main path signal remain challenging …

In this paper, we aim to develop a new subspace-based method for Direction Of Arrival
estimation (direction-finding) using coherent wide band (WB) or ultra-wide band (UWB) …

A novel direction-of-arrival (DOA) estimator is proposed for the mixed uncorrelated and
correlated wideband sources in the multipath environment. Firstly, the novel signal model is …

Orthogonality of Projected Subspace (TOPS) based Angle of Arrival (AOA) estimation
methods are computational complexity and spurious peaks. This work tries to explain the …

Since the space-air bistatic radar (SABR) system works in down-looking mode, it encounters
a severely broadened clutter spectrum and the clutter is range dependent. Thereby …

In recent years, researchers have tried to estimate the direction-of-arrival (DOA) of wideband
sources and several novel techniques have been proposed. In this paper, we compare six …

The performance of conventional direction of arrival (DOA) methods is susceptible to the
uncertainty of acoustic velocity in the underwater environment. To solve this problem, an …

Estimation of azimuth and elevation angles of both Angle of Arrival and Angle of Departure
is a challenging research topic in 5G smart antenna technology. The key contributions of this …
