چکیده

This letter investigates the impact of antenna element directivity on compressed sensing (CS)-based direction arrival (DOA) estimation employing uniform circular array (UCA) antenna. In CS-based approach, reconstruction accuracy sparse signals is determined by a matrix, which depends configuration in DOA estimation. our study, we analyze cross-correlation between column vectors matrix and clarify for various radiation patterns.

DOA Estimation of Smart Antenna Signal Based on MUSIC Algorithm

This paper presented a feature vector based spatial differential correlation DOA estimation algorithm. The algorithm uses the matrix properties, structure contains only spatial differential matrix of the correlation signal, and its characteristic value eigenvalue decomposition vectors, the value of each feature vector signal corresponds to a group of related, since the set of feature vectors co...

Accurate Determination of Antenna Directivity

The derivation of a formula for accurate estimation of the total radiated power from a transmitting antenna for which the radiated power density is known in a finite number of points on the far-field sphere is presented. The main application of the formula is determination of directivity from power-pattern measurements. The derivation is based on the theory of spherical wave expansion of electr...

Unmanned aerial vehicle field sampling and antenna pattern reconstruction using Bayesian compressed sensing

Antenna 3D pattern measurement can be a tedious and time consuming task even for antennas with manageable sizes inside anechoic chambers. Performing onsite measurements by scanning the whole 4π [sr] solid angle around the antenna under test (AUT) is more complicated. In this paper, with the aim of minimum duration of flight, a test scenario using unmanned aerial vehicles (UAV) is proposed. A pr...

A New Method of DOA Estimation for Uniform Antenna Array

A novel method of direction-of-arrival (DOA) estimation based on subarray beamforming for uniform circular arrays is proposed. In this method, the beamform manifold of uniform circular arrays is transformed via virtual structure, and then the virtual array is divided into two subarrrays. The target DOA is estimated from the phase shift between the reference signal and its phase-shifted version ...

The Estimation of DOA in Smart Antenna Systems

132 Abstract— Smart antennas systems are being the key solution to increase the spectral efficiency and improving the system performance in mobile communication. Smart antennas usually consist of a number of radiating elements (i.e. array antennas) whose individual excitation can be controlled by DSP (digital signal processor) in order to achieve the desired radiation pattern. The smart antenna...
