Digital Beamforming library
Unifying Software & Hardware
Click here to download data sheet Digital Beamforming library
Beamforming is very crucial algorithm module for several SONAR and RADAR applications. Real time implementation of the algorithm in FPGA is very essential to meet scanning and tracking applications. The UTS Digital Beamforming FPGA library enables fast and efficient realization of beamforming algorithm on Xilinx series FPGAs. The library is provided with multiple user settable options and allows to realize beam forming solutions for RADAR and SONAR and telemetry/tracking applications with linear and Planar array topology. Algorithm library for other configurations such as conformal or irregular array arrangements are provided based on customer requirements. The supplied product consists below modules.

1)Xilinx FPGA compatible NGCs (VHDL Source code optional)
2)MATLAB/OCTAVE simulation models
3)Scripts to generate coefficient files based on the Beamforming requirements.

User can provide the required options through GUI, as shown in figure. Additional options can be provided through scripts to generate the COEFF file and simulation models.

Release 2.1, Dec 2016
Array configuration
Array Element - Radiation pattern
The Array topology can be selected from any one of the following

(a) Uniform Linear Array (ULA)
(b) Uniform Circular Array (UCA)
(c) Uniform Planar Array (UPA)

Other array types such as planar circular array and conformal arrays can be supported based on user requirements(optional feature).
Each array element can be loaded from a predefined library of antenna models. The popular patch and Vivaldi radiation patterns are readily provided for different configurations.
As an optional feature, the Hyperbeam technique is supported to generate a narrow beam as compared to conventional beam with improved performance of SLL that depend on the variation of exponent parameter ().
Hyper Beamforming
Real time Beam switching
The tool provides the following types of beamforming Coefficient generation scripts for FPGA implementation.

Point beam
Auto scanning beam over given Az and El range
User Indexed beam switching

The coefficients are automatically scaled to match the required input and output dynamic ranges. The desired beam can be directly loaded through coefficient sets.
TR module compensation
The beam forming library can take measured phase and gain offsets of each TR module and applies compensation before substituting in the beamforming function.
Tapering and side lobe reduction
The options for tapering can be enabled to minimize the side lobe levels. Different parameterized functions are offered in the tool. In addition user can load own tapering functions or values.
Applications
Digital Beamformer based RADAR
Telemetry and tracking
Software defined radios
Smart Antenna based systems
EW Test equipment  & BITE
SONAR / Acoustics applications
