WebSep 30, 2024 · 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) signals. Subspace-based methods are well-established in the incoherent narrow band signals context; nevertheless, only a few of them are adapted to the case of WB or UWB … WebDec 1, 2010 · A new DOA estimation methodology is proposed based on incoherent signal subspace method (ISSM), which presents a criterion to select a single sub-band of the selected narrowband signals instead of scanning the whole signal spectrum. 10 Alternative to coherent signal subspace based method for buried objects localization

WebNov 22, 2024 · The wideband signal-subspace algorithms can be classified into two different types: the incoherent signal-subspace method (ISM) [ 9] and the coherent signal-subspace method (CSM) [ 10 ]. ISM divides the wideband sources into a set of nonoverlapping narrowband discrete components. Incoherent scattering is a type of scattering phenomenon in physics. The term is most commonly used when referring to the scattering of an electromagnetic wave (usually light or radio frequency) by random fluctuations in a gas of particles (most often electrons). The most well known practical application is known as incoherent scatter radar theory, a ground-based technique for studying the Earth's ionosphere first proposed by Professor William E. Gordon in …
