For example, a commonly used beamforming technique--independent weighting control over each antenna array element
, with a transmit/receive (T/R) module dedicated to each element is simple, but oftentimes not practical due to cost, space, and power limitations.
To achieve better beamforming control and flexibility for the future's systems, it would be ideal to have independent weighting control over each antenna array element
, with a transmit/receive (T/R) module dedicated to each element.
A specific array element
is referenced by putting its element number in parentheses following the array name.
In a standard phased array, it is assumed that identical transmitted signal is emitted from the individual array element
, excluding the amplitudes and phases.
Ultrasonic phased array can achieve the high efficiency detection of the structure by using the orderly stack of sound beam emitted from each array element
and is significant for structural health monitoring.
Therefore, one array element
provides all the data necessary to compute one cell.
The seminar on October 22 will feature installed sound elements with a demonstration of K-array's flexible, array element
speaker, the Anakonda KAN200 and the KZ10, an ultra-miniaturised line-array element.
In all the considered cases the array is symmetric, and the optimization goal is that of determining the array element
excitation coefficients, [a.sub.n], the position, normalized with respect to the wavelength [lambda], [d.sub.n]/[lambda], and the minimum number 2N of array elements
that allows to satisfy the array radiation constraints.
The authors proposed a wideband printed dipole antenna in , which will be used as the antenna array element
in this paper.
is the open circuit voltage induced by the ith impinging wave at the nth planar array element
located in the position [r.sub.n] = ([x.sub.n], [y.sub.n]).
