Frequency invariant beamforming for two-dimensional and three-dimensional arrays
نویسندگان
چکیده
A novel method for the design of two-dimensional (2-D) and three-dimensional (3-D) arrays with frequency invariant beam patterns is proposed. By suitable substitutions, the beam pattern of a 2-D or 3-D arrays can be regarded as the 3-D or 4-D Fourier transform of its spatial and temporal parameters. Since frequency invariance can be easily imposed in the Fourier domain, a simple design method is derived. Design examples for the 2-D case are provided.

Improving beampatterns of two-dimensional random arrays using convex optimization.
Sensors are becoming ubiquitous and can be combined in arrays for source localization purposes. If classical conventional beamforming is used, then random arrays have poor beampatterns. By pre-computing sensor weights, these beampatterns can be improved significantly. The problem is formulated in the frequency domain as a desired look direction, a frequency-independent transition region, and th...
متن کاملAdaptive beamforming in row-column addressed arrays for 3D ultrasound imaging
In recent years, to reduce the complexity of implementation, the use of 2D arrays with restricted row-column addressing has been considered for 3D ultrasound imaging. In this paper, two methods of adaptive beamforming based on the minimum variance method are represented in such a way that the computational load is much less than using the full adaptive beamforming method. In both proposed metho...

designing FIR fan filters suitable for the multibeam forming network of the wideband beamspace adaptive array. Characteristics were approximated through the combination of spectral transformation and the window method so that those beam patterns that included the sidelobe characteristics of the resulting fan filters were virtually frequency independent. Using the fan filters designed by the pro...
متن کاملDistance-Aware Beamforming for Multiuser Secure Communication Systems
Typical cryptography schemes are not well suited for low complexity types of equipment, e.g., Internet of things (IoT) devices, as they may need high power or impose high computational complexity on the device. Physical (PHY) layer security techniques such as beamforming (in multiple antennas systems) are possible alternatives to provide security for such applications. In this paper, we consid...
متن کاملDesign, implementation, and comparison of guided wave phased arrays using embedded piezoelectric wafer active sensors for structural health monitoring
Phased array can interrogate large structural areas from a single location using ultrasonic guided waves generated by tuned piezoelectric wafer active sensors that are permanently attached (embedded) to the structure. Various array parameters determine the array beamforming and steering characteristics. This paper aims to bring up several one or two dimension array designs and research on their...
