چکیده
A method for direction of arrival (DOA) estimation and object localization based on 1-bit time-modulated reflectarray (TMRA) is presented. The multi-harmonic multi-beam (MHMB) characteristic TMRA analyzed firstly to reveal the mapping relationship between target’s angular feature received spectrum feature. Then operating principle perception procedures single multiple targets scenarios are discussed in detail. Benefited from relationship, proposed shows flexibility simultaneous multi-target detection, which difficult realize by conventional methods. Furthermore, enables environment-perception capability existing without increasing system complexity, making it suitable realization a low-cost multifunctional reconfigurable intelligent surface (RIS).

In this article, we present a novel method for high-resolution joint direction-of-arrivals (DOA) and multi-pitch estimation based on subspaces decomposed from a spatio-temporal data model. The resulting estimator is termed multi-channel harmonic MUSIC (MC-HMUSIC). It is capable of resolving sources under adverse conditions, unlike traditional methods, for example when multiple sources are impin...

The present work introduces a novel algorithm for Direction-ofarrival (DOA) estimation of signals in the multi-path environment. The technique relies on transient smoothing way to extract the coherence properties of sub-array, and restores the rank of the data covariance matrix. After processed, the multipath channel signals were de-correlation and can be processed by traditional DOA estimation...
