چکیده
Electromagnetic vector sensor (EMVS) array is a new type of array to obtain the electromagnetic signal spatial and polarization domain information, which has the broad application prospect in the communication technique, signal detection technique (SDT), mobile communication and so on [1]-[23]. Direction of arrival (DOA) estimation based on the EMVS array has become a hot topic in the research field of signal processing, and it has made many valuable research results [1], [4]-[6], [8]-[12], [15]-[22]. The authors in literatures [2]-[12] have studied the direction finding parameter estimation of complete EMVS array, the parameter estimation of incomplete EMVS has been discussed in literatures [13]-[18], the direction finding and positioning parameter estimation of

Quaternion-based Finite-time Sliding Mode Controller Design for Attitude Tracking of a Rigid Spacecraft during High-thrust Orbital Maneuver in the Presence of Disturbance Torques
In this paper, a quaternion-based finite-time sliding mode attitude controller is designed for a spacecraft performing high-thrust orbital maneuvers, with cold gas thrusters as its actuators. The proposed controller results are compared with those of a quaternion feedback controller developed for the linearized spacecraft dynamics, in terms of settling time, steady-state error, number of thrust...
متن کاملRobust System Architecture for DOA Estimation based on Total Forward Backward Matrix Pencil Algorithm
Radio Direction Finding (DF) is a technique that identifies the bearing angle or the coordinates of an incoming radio signal(s). The primary function of DF is to get the Direction of Arrival (DOA) information. In this paper, we propose the robust system architecture for DOA estimation using the Total Forward Backward Matrix Pencil Method (TFBMP). This method works directly on signal samples of ...
متن کاملIterative algorithm for the generalized $(P,Q)$-reflexive solution of a quaternion matrix equation with $j$-conjugate of the unknowns
In the present paper, we propose an iterative algorithm for solving the generalized $(P,Q)$-reflexive solution of the quaternion matrix equation $overset{u}{underset{l=1}{sum}}A_{l}XB_{l}+overset{v} {underset{s=1}{sum}}C_{s}widetilde{X}D_{s}=F$. By this iterative algorithm, the solvability of the problem can be determined automatically. When the matrix equation is consistent over...
متن کاملDirection Finding with Uniform Circular Arrays via Phase Mode Excitation and Beamspace Root-music
Beamspace Root-MUSIC is a computationally efficient, beamspace implementation of Root-MUSIC developed recently for use in conjunction with a uniform linear array (ULA). Employing B real-valued beams having all but B-1 nulls in common, the major computations in Beamspace Root-MUSIC are a BxB real-valued eigenvalue decomposition (EVD) and the rooting of a polynomial of order B-1. Recently, Beamsp...
متن کاملA Quaternion Firefly Algorithm to Solve a Multi-row Facility Layout Problem (RESEARCH NOTE)
In this paper, a quaternion firefly algorithm is utilized to solve a multi-row facility layout design problem with the objective of minimizing the total cost of transportation. A quaternion firefly algorithm takes the motion of the firefly as a quaternion one. Consequently, the solution space is explored more accurately and the answers are of higher quality. That is, the answers are considerabl...
